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 β- and β+ transitions and two neutrino double beta decay nuclear matrix elements have been calculated for 128,130Te→128,130Xe transitions. The obtained results have been compared with the corresponding experimental data and other theoretical results. © 2006 American Institute of Physics.
