Abstract
The two neutrino double beta decay of 128, 130Te isotopes to the ground state of the 128, 130Xe isotopes has been calculated by including the contributions coming from the isobar analog states in the intermediate nuclei. The nuclear matrix elements have been computed by using the proton–neutron quasi-particle random phase approximation (pnQRPA). The broken isospin invariance of the nuclear part of the total nucleus Hamiltonian has been restored for the study of the isobar analogue excitations in the intermediate nuclei. The SU(4) symmetry violation in the shell model approximation has been considered for the investigation of the Gamow–Teller states.
