Pavel Tcherenkov

Pavel Alekseyevitch Tcherenkov (), (July 28th 1904 - January 6th 1990) is a Russian physicist , Nobel Prize of physics in 1958.

Biography

Tcherenkov is born in Nizhniaya Chigla, in the Oblast de Voronej in 1904, of Aleksei and Mariya Cherenkov. In 1930 it Marie with Marya Putintseva. He studies at the department of physics and mathematics of the Université of State de Voronej. in 1938 he becomes researcher with the Institut of physique Lebedev.

Tcherenkov dies in Moscow the January 6th 1990 and is buried with the Cimetière of Novodevitchi.

Research

Tcherenkov is interested so that one calls the Effet Tcherenkov nowadays. It was known since 1910 that water, under the effect of a radioactive source, emits a blue radiation. Tcherenkov proves between 1934 and 1937 that the Radiation produced is independent of the composition of the Liquide, which was in disagreement with the theory of the Fluorescence then allowed to explain this phenomenon. His/her colleagues Igor Tamm and Ilja Frank give a rigorous and simple mathematical explanation. The Tcherenkov effect is produced by the Effect Compton, caused by the gamma rays due to the radioactivity, on the electrons of the medium. Its work their is worth the Nobel Prize of physics in 1958 “For the discovery and the interpretation of the Effet Tcherenkov”. The Tcherenkov effect became an instrument essential to the Physique particles, it allows the construction of simple detectors of particles which make it possible to deduce the mass and the speed of a particle.
