Sir James Chadwick (20 October 1891 – 24 July 1974) was an English physicist who received the Nobel Prize in Physics in 1935 for his discovery of the neutron. In 1941, he wrote the final draft of the MAUD Report , which inspired the U.S. government to begin serious atom bomb research efforts.
James Chadwick at the 1933 Solvay Conference. Chadwick had discovered the neutron the year before while working at Cavendish Laboratory.. The discovery of the neutron and its properties was central to the extraordinary developments in atomic physics in the first half of the 20th century.
The neutron was discovered by James Chadwick at the Cavendish Laboratory at the University of Cambridge in February 1932. [1] [2] Two months later, his Cavendish colleagues John Cockcroft and Ernest Walton split lithium atoms with accelerated protons.
Atomic theory is the scientific theory that matter is composed of ... but James Chadwick found that the ionization effect was too strong for it to be due to ...

1936 Eugene Wigner develops the theory of neutron absorption by atomic nuclei; 1936 Hermann Arthur Jahn and Edward Teller present their systematic study of the symmetry types for which the Jahn–Teller effect is expected [8] 1937 Carl Anderson proves experimentally the existence of the pion predicted by Yukawa's theory.

The fact that the atomic nucleus is composed of protons and neutrons was rapidly accepted and Chadwick was awarded the Nobel Prize in Physics in 1935 for his discovery. [ 14 ] The modern form of the whole number rule is that the atomic mass of a given elemental isotope is approximately the mass number (number of protons plus neutrons) times an ...
