Donald Hill Perkins CBE FRS (born 1925) is a British physicist and an Emeritus Professor at the University of Oxford. He achieved great success in the field of particle physics and is also known for his books. Perkins was born in 1925 and educated at Imperial College London. In 1945 he received his B.Sc. and 1948, a Ph.D. From 1949 he worked at Bristol University and in 1955/56 at the Lawrence Radiation Laboratory in Berkeley. In 1956 he received the post of reader in Bristol University. In 1963/64 he conducted research at CERN. In 1965 he became Oxford professor of elementary particle physics. There he built, along with Ken W. Allen, the new Department of Nuclear Physics. In 1976/77 and 1983/84 he returned to CERN. In 1998 he retired and became Emeritus Fellow of St Catherine's College, Oxford. ==Achievements== Perkins' earliest achievements include the discovery of the negative pion in cosmic radiation. At Berkeley, he worked with accelerators on K-mesons and the annihilation of protons and antiprotons, at CERN in neutrino scattering experiments. He made important pioneering discoveries in regard to the weak neutral current (Gargamelle experiment) and the experimental verification of quantum chromodynamics. In 1982 he explored the possible proton decay, and found a first indication of neutrino oscillations. In the applied field, he worked on the design of the HERA storage ring at DESY in 1961 and worked on cancer therapy with pions. Perkins in 1959 published his first textbook, together with C. F Powell and P. Fowler, on the theme of the emulsion technique applied to cosmic rays, nuclear, and particle physics. His ''Introduction to High Energy Physics'' is a global standard work on particle physics. Most recently he published in 2003 ''Particle Astrophysics''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Donald Hill Perkins」の詳細全文を読む スポンサード リンク
