Sir James Chadwick, CH, FRS (20 October 1891 – 24 July 1974) was an English physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932. In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atom bomb research efforts.

La nature essentielle du noyau atomique a été finalement établie avec la découverte du neutron par James Chadwick en 1932 6 et par la détermination qu'il s'agissait d'une nouvelle particule élémentaire, distincte du proton 7, 8:55.
James Chadwick was a British physicist who discovered the neutron in 1932 and worked on nuclear transmutation and fission. He was a student and colleague of Rutherford, a Fellow of the Royal Society, and a Master of Gonville and Caius College, Cambridge.
James Chadwick discovered the neutron, a neutral particle with about the same mass as a proton, in 1932. He proved that the radiation emitted by beryllium was not electromagnetic, but a new type of particle proposed by Ernest Rutherford.
