Georgii Timofeevich Zatsepin was born May 28, 1917 in Moscow.

G.T.Zatsepin graduated from the Physics Department of Moscow University in 1941 and spent three years working on the aircraft building plant in Moscow, then in Irkutsk. In 1944 he entered the graduate school of Physics, Moscow State University and in 1950 the Faculty he defended his thesis on "The range of densities of extensive air showers". From this year G.T.Zatsepin works in the PN Lebedev Physical Institute of the USSR Academy of Sciences as a senior researcher. In 1954 he defended his doctoral dissertation on the theme "Nuclear cascade process as a basis for the development of the EAS." In 1958 he was awarded the title of professor. Since 1960 G.T.Zatsepin is head of the Laboratory of FIAN, and since 1970 - head of the department in the newly formed Institute for Nuclear Research, USSR Academy of Sciences. All this time, since 1945, G.T.Zatsepinrabotaet part-time at the department, academician DVSkobeltsyn formed at the Physics Department of Moscow State University, later known as the Department of Cosmic Rays and Space Physics, and since 1982. to 2005. He is the head of this department.

In 1968. G.T.Zatsepin elected a corresponding member of the Academy of Sciences of the USSR, and in 1981. - A full member of the Academy of Sciences of the USSR.

G.T.Zatsepinym created a large scientific school of theoretical and experimental cosmic ray physics, neutrino physics and astrophysics that extends far beyond the borders of Russia and play a greater role in Europe, America and Asia.

G.T.Zatsepin formulated entirely new patterns of development of the EAS through open their nuclear cascade process and received the main characteristics of this process, as well as proposed and created a new technique for the study of EAS, implemented under his leadership prisozdanii installations at MSU and in the Pamirs.

In the early 60s G.T.Zatsepin begins study of the penetrating component of cosmic radiation - muons and neutrinos, lays the foundation for a completely new directions - neutrino astronomy and neutrino astrophysics. The neutrino laboratory he created at FIAN develop methods of detecting solar neutrinos, allowing for a neutrino spectroscopy of the Sun, to obtain information about the thermonuclear reactions that occur in the solar interior. Under the leadership of G.T.Zatsepina and AE Chudakov in the North Caucasus, Baksan River valley, the world`s first neutrino observatory designed to study neutrinos and muons was built. For the creation of this unit and holding her G.T.Zatsepinu research in 1998 he was awarded the State Prize.

G.T.Zatsepinym and his colleagues obtained results of fundamental importance. With gallium-germanium method detected deficit neutrino radiation of low energy, born in the reactions of the hydrogen cycle of the Sun, which can not be explained by existing theories.

G.T.Zatsepinym course of lectures "atomic nucleus", "Neutrinos and Neutrino Astrophysics", "Space and cosmic radiation."

In 1951 G.T.Zatsepinu awarded the State Prize for the discovery of the nuclear cascade process, in 1982, the Lenin Prize for the creation of Yakutsk on the study of cosmic rays.

Zacepin awarded the Order of the Red Banner of the October Revolution, the medal "For Valiant Labor in the Great Patriotic War."

He has published over 300 scientific papers. Major works: "The collapse of the neutrino in gauge theories" (1978g.), "Neutrinos and Neutrino Astrophysics" (1980g.), "Neutrino" (1980).
