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

Abstract

Based on Pyatov's method, the low-lying Gamow-Teller (GT) 1(+) state energies and log(ft) values for Sb-128,Sb-130,Sb-132 and I-132,I-134,I-136 isotopes have been calculated. In this method, the strength parameter of the effective spin-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.
