Beta-transition properties for neutron-rich Sn and Te isotopes by Pyatov method

摘要

Based on Pyatov's method, the low-lying Gamowa€“Teller (GT) 1+ state energies and log(e?‘“e?‘?) values for 128,130,132Sb and 132,134,136I isotopes have been calculated. In this method, the strength parameter of the effective spina€“isospin interaction is found by providing the commutativity of the GT operator with the central part of the nuclear Hamiltonian. The problem has been solved within the framework of RPA. The calculation results have been compared with the corresponding experimental data.
