GAMOW THEORY OF ALPHA DECAY PDF

His predictions of cosmic microwave background radiation and his explanation of the present levels of hydrogen and helium in the universe both lent important theoretical support to the Big Bang theory. Georgiy Antonovich Gamov was born on 4 March in Odessa in the Russian Empire now in Ukraine to ethnic Russian parents, both of whom were teachers. His mother died when he was 9 years old and he was brought up by his father. His education at the local gymnasium was often interrupted by shelling during the First World War, so he was to a large extent self-taught. His education continued at the Novorossiya University in Odessa from to , and then at the University of Leningrad from , where he studied optics and, later, cosmology. He also worked on stellar physics with Robert Atkinson and Fritz Houtermans.

In addition, his work on deoxyribonucleic acid DNA made a basic contribution to modern genetic theory. Gamow attended Leningrad now St. Petersburg University, where he studied briefly with A. Friedmann , a mathematician and cosmologist who suggested that the universe should be expanding.

For example, performing the calculation for uranium shows that alpha particle emission would need the only 5. Most of this disintegration energy becomes the kinetic energy of the alpha particle itself, although to maintain conservation of momentum part of this energy becomes the recoil of the nucleus itself. However, since the mass numbers of most alpha-emitting radioisotopes exceed , far greater than the mass number of the alpha particle 4 the part of the energy going to the recoil of the nucleus is generally quite small. Quantum mechanics, however, allows the alpha particle to escape via quantum tunneling.

Gamow’s Theory of Alpha-Decay

For example, performing the calculation for uranium shows that alpha particle emission would need the only 5. Most of this disintegration energy becomes the kinetic energy of the alpha particle itself, although to maintain conservation of momentum part of this energy becomes the recoil of the nucleus itself. However, since the mass numbers of most alpha-emitting radioisotopes exceed , far greater than the mass number of the alpha particle 4 the part of the energy going to the recoil of the nucleus is generally quite small. Quantum mechanics, however, allows the alpha particle to escape via quantum tunneling. The quantum tunneling theory of alpha decay, independently developed by George Gamow [4] and Ronald Wilfred Gurney and Edward Condon in , [5] was hailed as a very striking confirmation of quantum theory.
