James Chadwick (1891-1974) was a British physicist who discovered the neutron in 1932. The neutron completed the basic proton-neutron picture of atomic nuclei.
Neutron discovery
Chadwick interpreted penetrating neutral radiation from beryllium as a new neutral particle with mass close to that of the proton. The discovery made nuclear structure clearer and transformed nuclear physics.
The neutron later became central to nuclear reactions, isotope physics, fission, and the quantum description of nuclei.
