Wolfgang Pauli proposed another kind of particle on 4 December in order to explain the continuous spectrum of beta radiation that Chadwick had reported in Since not all of the energy of beta radiation could be accounted for, the law of conservation of energy appeared to be violated, but Pauli argued that this could be redressed if another, undiscovered, particle was involved.

Fermi renamed it the neutrino , Italian for "little neutron". Rudolf Peierls and Hans Bethe calculated that neutrinos could easily pass through the Earth, so the chances of detecting them were slim.

With the onset of the Great Depression in the United Kingdom , the government became more parsimonious with funding for science.

At the same time, Lawrence's recent invention, the cyclotron , promised to revolutionise experimental nuclear physics, and Chadwick felt that the Cavendish laboratory would fall behind unless it also acquired one.

He therefore chafed under Rutherford, who clung to the belief that good nuclear physics could still be done without large, expensive equipment, and turned down the request for a cyclotron.

Chadwick was himself a critic of Big Science in general, and Lawrence in particular, whose approach he considered careless and focused on technology at the expense of science.

When Lawrence postulated the existence of a new and hitherto unknown particle that he claimed was a possible source of limitless energy at the Solvay Conference in , Chadwick responded that the results were more likely attributable to contamination of the equipment.

This was another major discovery, but the Oliphant-Rutherford particle accelerator was an expensive state-of-the-art piece of equipment.

In March , Chadwick received an offer of the Lyon Jones Chair of physics at the University of Liverpool , in his wife's home town, to succeed Lionel Wilberforce.

The laboratory was so antiquated that it still ran on direct current electricity, but Chadwick seized the opportunity, assuming the chair on 1 October The university's prestige was soon bolstered by Chadwick's Nobel Prize, which was announced in November Chadwick set about acquiring a cyclotron for Liverpool.

A local cable manufacturer donated the copper conductor for the coils. The cyclotron's ton magnet was manufactured in Trafford Park by Metropolitan-Vickers , which also made the vacuum chamber.

At Liverpool the Medicine and Science faculties worked together closely. Chadwick was automatically a committee member of both faculties, and in he was appointed to a commission headed by Lord Derby to investigate the arrangements for cancer treatment in Liverpool.

Chadwick anticipated that neutrons and radioactive isotopes produced with the inch cyclotron could be used to study biochemical processes, and might become a weapon in the fight against cancer.

In Germany, Otto Hahn and Fritz Strassmann bombarded uranium with neutrons, and noted that barium , a lighter element, was among the products produced.

Hitherto, only the same or heavier elements had been produced by the process. In January , Meitner and her nephew Otto Frisch astounded the physics community with a paper that explained this result.

They calculated that this would result in the release of about MeV , implying an energy release orders of magnitude greater than chemical reactions, [68] and Frisch confirmed their theory experimentally.

Chadwick did not believe that there was any likelihood of another war with Germany in , and took his family for a holiday on a remote lake in northern Sweden.

The news of the outbreak of the Second World War therefore came as a shock. Determined not to spend another war in an internment camp, Chadwick made his way to Stockholm as fast as he could, but when he arrived there with his family, he found that all air traffic between Stockholm and London had been suspended.

They made their way back to England on a tramp steamer. When he reached Liverpool, Chadwick found Joseph Rotblat , a Polish post-doctoral fellow who had come to work with the cyclotron, was now destitute, as he was cut off from funds from Poland.

Chadwick promptly hired Rotblat as a lecturer, despite his poor grasp of English. In October , Chadwick received a letter from Sir Edward Appleton , the Secretary of the Department of Scientific and Industrial Research, asking for his opinion on the feasibility of an atomic bomb.

Chadwick responded cautiously. He did not dismiss the possibility, but carefully went over the many theoretical and practical difficulties involved.

Chadwick decided to investigate the properties of uranium oxide further with Rotblat. Instead of looking at unenriched uranium oxide, they considered what would happen to a sphere of pure uranium, and found that not only could a chain reaction occur, but that it might require as little as 1 kilogram 2.

A special subcommittee of the Committee for the Scientific Survey of Air Warfare CSSAW , known as the MAUD Committee , was created to investigate the matter further.

It was chaired by Sir George Thomson and its original membership included Chadwick, along with Mark Oliphant, John Cockcroft and Philip Moon.

In July , Chadwick was chosen to write the final draft of the MAUD Report, which, when presented by Vannevar Bush to President Franklin D.

Roosevelt in October , inspired the U. Pegram and Harold Urey visited Britain to see how the project, [82] now known as Tube Alloys , [83] was going, Chadwick was able to tell them: "I wish I could tell you that the bomb is not going to work, but I am 90 per cent sure that it will.

In a recent book about the Bomb project, Graham Farmelo wrote that "Chadwick did more than any other scientist to give Churchill the Bomb.

Chadwick was tested almost to the breaking point. Chadwick later said that he realised that "a nuclear bomb was not only possible—it was inevitable.

Sooner or later these ideas could not be peculiar to us. Everybody would think about them before long, and some country would put them into action".

Owing to the danger from aerial bombardment, the Chadwicks sent their twins to Canada as part of a government evacuation scheme.

It would have to be built in America. The matter of cooperation had to be taken up at the highest level. In September , the Prime Minister , Winston Churchill , and President Roosevelt negotiated the Quebec Agreement , which reinstated cooperation between Britain, the United States and Canada.

Chadwick, Oliphant, Peierls and Simon were summoned to the United States by the director of Tube Alloys, Sir Wallace Akers , to work with the Manhattan Project.

The Quebec Agreement established a new Combined Policy Committee to direct the joint project. The Americans disliked Akers, so Chadwick was appointed technical advisor to the Combined Policy Committee, and the head of the British Mission.

Leaving Rotblat in charge in Liverpool, Chadwick began a tour of the Manhattan Project facilities in November , except for the Hanford Site where plutonium was produced, which he was not allowed to see.

He became the only man apart from Groves and his second in command to have access to all the American research and production facilities for the uranium bomb.

Observing the work on the K gaseous diffusion facility at Oak Ridge, Tennessee , Chadwick realised how wrong he had been about building the plant in wartime Britain.

The enormous structure could never have been concealed from the Luftwaffe. Chadwick accepted that the Americans did not need British help, but that it could still be useful in bringing the project to an early and successful conclusion.

Working closely with the director of the Manhattan Project, Major General Leslie R. Requests from Groves via Chadwick for particular scientists tended to be met with an immediate rejection by the company, ministry or university currently employing them, only to be overcome by the overriding priority accorded to Tube Alloys.

Although he had more knowledge of the project than anyone else from Britain, [98] Chadwick had no access to the Hanford site.

Lord Portal was offered a tour of Hanford in Groves replied that he could, but if he did then 'Portal will not see very much'. By early , Chadwick was spending most of his time in Washington, D.

Laurence , the New York Times reporter attached to the Manhattan Project, wrote that "never before in history had any man lived to see his own discovery materialize itself with such telling effect on the destiny of man.

Shortly after the war ended, Chadwick was appointed to the Advisory Committee on Atomic Energy ACAE. He was also appointed as the British scientific advisor to the United Nations Atomic Energy Commission.

He clashed with fellow ACAE member Patrick Blackett , who disagreed with Chadwick's conviction that Britain needed to acquire its own nuclear weapons; but it was Chadwick's position that was ultimately adopted.

He returned to Britain in , to find a country still beset by wartime rationing and shortages. At this time, Sir James Mountford, the Vice Chancellor of the University of Liverpool, wrote in his diary "he had never seen a man 'so physically, mentally and spiritually tired" as Chadwick, for he "had plumbed such depths of moral decision as more fortunate men are never called upon even to peer into In , Chadwick accepted an offer to become the Master of Gonville and Caius College.

The job was prestigious but ill-defined; the Master was the titular head of the College, but authority actually resided in a council of 13 fellows, of whom one was the Master.

As Master, Chadwick strove to improve the academic reputation of the college. He increased the number of research fellowships from 31 to 49, and sought to bring talent into the college.

In what became known as the Peasants' Revolt, fellows led by Patrick Hadley voted an old friend of Chadwick's off the council and replaced him with Bauer.

More friends of Chadwick's were removed over the following years, and he retired in November It was during his mastership that Francis Crick , a PhD student at Gonville and Caius College, and James Watson discovered the structure of DNA.

He became more frail, and seldom left his flat, although he travelled to Liverpool for celebrations of his eightieth birthday.

A lifelong atheist, he saw no reason to adopt religious faith in later life. He died in his sleep on 24 July His papers are held at the Churchill Archives Centre in Cambridge, and are accessible to the public.

When World War I broke out, he was imprisoned in a camp for civilians at Ruhleben. He spent the entire war there but nevertheless was able to accomplish some scientific work.

After the war ended, Chadwick returned to England to study under Rutherford at the University of Cambridge. He received a doctorate in , and in he was appointed assistant director of research at the Cavendish Laboratory, Cambridge.

There he and Rutherford studied the transmutation of elements by bombarding them with alpha particles and investigated the nature of the atomic nucleus, identifying the proton , the nucleus of the hydrogen atom , as a constituent of the nuclei of other atoms.

After the discovery of the proton, physicists had surmised that there were likely additional particles in the atomic nucleus.

Elements heavier than hydrogen had a greater atomic mass than their atomic number the number of protons. Theories for the additional particles included additional protons whose charge was shielded by electrons in the nucleus or an unknown neutral particle.

The Joliot-Curies hypothesized that this radiation was gamma-rays. Chadwick was convinced that alpha particles did not have enough energy to produce such powerful gamma-rays.

He performed the beryllium bombardment experiments himself and interpreted that radiation as being composed of particles of mass approximately equal to that of the proton but without electrical charge—neutrons.
