Dubrovska Y. Relativistic calculation of characteristics of the ?-decay of nuclei on the basis of optimized Dirac - Fock method

Dissertation is devoted to carrying out new approach relativistic approach to calculating characteristics of nuclear beta decay with an account for relativistic, exchange -correlation, nuclear and radiative effects in the wave functions, the chemical atoms surrounding within optimized Dirac-Fock model of atom and gauge-invariant perturbation theory. It is used in calculation of the whole set of permitted ? transitions. It is carried out a calculation of an influence for the atomic field type, exchange-correlation and chemical environment effects, different definitions of the Fermi function on values of this parameter and beta decay characteristics. The obtained data can be used in a whole number of applications, including nuclear, atomic and laser physics, accelerator physics etc.
