Anton Panteleimonovich Komar (born 30.05.1904) is a Soviet physicist and an academician of the Academy of Sciences of the Ukrainian SSR (1948). He was born in the village of Berezna (now in Kiev Region). He graduated from the Kiev Polytechnic Institute (1930). In 1930 — 36 he worked at the Leningrad Physico-Technical Institute and in 1936 — 47 at the Urals Physico-Technical Institute (Sverdlovsk), at the same time heading a department at Urals University (1937—47), and in 1948-50 he was at the Physical Institute of the USSR Academy of Sciences. From 1950 he has worked at the Leningrad Physico-Technical Institute (director in 1950 —57), and in 1951—69 he was also head of a department at the Leningrad Polytechnic Institute.
His research concerned nuclear physics, the methods and techniques of nuclear experiments, physical electronics, the physics and technology of accelerators, and the physics of metals and ferrites. He carried out a series of studies of the galvanomagnetic and electrical properties of ordering alloys and discovered in them the phenomenon of a change of sign of the Hall constant. He brought into operation (1946) the first betatron in the USSR. Together with V. I. Veksler he took part in the creation of electron accelerators, in particular a 250 MeV synchrotron. His work (1950-60) on photonuclear reactions was a contribution to the understanding of the mechanism by which gamma quanta interact with nuclei. He developed methods of electron and ion microscopy at the level of atomic dimensions.
USSR State Prize (1951).
