Özet

Based on Pyatov-Salamov method, spin-isospin (Gamow-Teller) effective interaction strength parameter has been found self-consistently. Then, the problem has been solved within the framework of QRPA. Gamow-Teller matrix elements for both beta(-) and beta(+) transitions and two neutrino double beta decay nuclear matrix elements have been calculated for Te-128,Te-130 -> Xe-128,Xe-130 transitions. The obtained results have been compared with the corresponding experimental data and other theoretical results.
