Sir John Douglas Cockcroft (* 27. Mai 1897 in Todmorden , England; † 18. September 1967 in Cambridge ) war ein britischer Kernphysiker und Nobelpreisträger .
Sir John Douglas Cockcroft OM KCB CBE FRS (27 May 1897 – 18 September 1967) was an English physicist who shared with Ernest Walton the Nobel Prize in Physics in 1951 for splitting the atomic nucleus, and was instrumental in the development of nuclear power.
The Nobel Prize in Physics 1951 was awarded jointly to Sir John Douglas Cockcroft and Ernest Thomas Sinton Walton "for their pioneer work on the transmutation of atomic nuclei by artificially accelerated atomic particles"
John Cockcroft was a British physicist who developed a device to accelerate protons and bombard lithium nuclei, causing nuclear fission. He shared the Nobel Prize in Physics in 1951 with Ernest Walton for their pioneer work on transmutation of atomic nuclei.
Cockcroft, who was both a student and Fellow at St John’s, is perhaps best known for the pioneering 1932 experiment in which he and his fellow researcher, Ernest Walton, transformed the nucleus of a lithium atom by bombarding it with high-energy particles.
Sir John Douglas Cockcroft (born May 27, 1897, Todmorden, Yorkshire, Eng.—died Sept. 18, 1967, Cambridge, Cambridgeshire) was a British physicist, joint winner, with Ernest T.S. Walton of Ireland, of the 1951 Nobel Prize for Physics for pioneering the use of particle accelerators in studying the atomic nucleus.
