The study of gamow-teller decays in odd mass nuclei by Pyatov-Salamov method

In this thesis, the super symmetry property of the isoscalar term in the nuclear part of the shell model mean field potential violated has been restored by using Pyatov-Salamov method. An additional effective interaction term coming from this restoration contributes to the total Hamiltonian. The beta decay processes in even mass and odd mass nuclei have been searched by using QRPA method. Those processes include the energy distribution of GT transition strength and GT resonance in the 74Kr, 76Kr and 116Sn, and 75-77Kr, 117Sn. The obtained results have been compared with the corresponding experimental data and the other theoretical calculation results. Calculation results show that the restoration of the broken super symmetry property of the isoscalar term of the nuclear part in shell model potential is important. Additionally, and total transition strength in odd mass nuclei have been calculated by using Pyatov-Salamov method when it is compared with the other methods, it gets closer to the corresponding experimental data. Therefore, Pyatov-Salamov method is important in these type of calculations.
