Özet

We try to give a detailed analysis of the 2 nu beta(-)beta(-) decay rates to the final ground states for decay emitters: (70)ZN, Se-80, Kr-86, (94)zr, Ru-104, (110)pd, Cd-114 and Sn-124. The nucleon nucleon residual interaction potential is defined according to Pyatov's restoration method. The nuclear matrix element for 2 nu beta(-)beta(-) decay is obtained by including the virtual contributions coming from the isobar analogue excitations within the framework of proton neutron quasi-particle random phase approximation (pnQRPA). The calculated decay rates are compared with mean field, schematic model and other calculations.
