Physics records
| Date | Person | Event | Place | Description |
|---|---|---|---|---|
| 27 February 1932 | James Chadwick Physicist | Possible Existence of a Neutron | Cambridge, Great Britain | Publishes evidence that the penetrating beryllium radiation consists of neutral particles with roughly proton mass. |
| June 1932 | James Chadwick Physicist | The Existence of a Neutron | Cambridge, Great Britain | Publishes a fuller experimental account establishing the neutron as a distinct nuclear particle. |
| 1932 | James Chadwick Physicist | Discovery of Neutron | Cambridge, Great Britain | Discovers the neutron, clarifying nuclear structure and explaining how isotopes of the same element can share an atomic number while differing in mass. |
| 1932 | James Chadwick Physicist | Neutron Mass Estimate | Cambridge, Great Britain | Uses recoil measurements from several light elements to estimate the mass of the newly identified neutron. |
| December 1935 | James Chadwick Physicist | Nobel Prize for Neutron Discovery | Stockholm, Great Britain | Receives the Nobel Prize in Physics for the discovery of the neutron. |
| 1935 | James Chadwick Physicist | Nobel Prize | Stockholm, Great Britain | Receives the Nobel Prize in Physics for discovering the neutron, a neutral nuclear particle fundamental to understanding atomic nuclei. |
| 15 July 1941 | James Chadwick Physicist | MAUD Committee | Liverpool, Great Britain | Supports the MAUD conclusion on uranium weapon feasibility while based at Liverpool. |
