      More Details Abstract Fulltext PDF

      Transition charge densities (TCD) for 0+ → 21+ excitation have been calculated for70,72,74,76Ge nuclei within microscopic variational framework employing 2p3/2, 1f5/2, 2p1/2 and 1g9/2 valence space. The calculated TCDs for different monopole variants of Kuo interaction are compared with available experimental results. Other systematics like reduced transition probabilitiesB(E2) and static quadrupole momentsQ(2) are also presented. It is observed that the transition density study acts as a sensitive probe for discriminating the response of different parts of effective interactions.

      More Details Abstract Fulltext PDF

      The two-neutrino double beta decay of96Zr isotope for 0+ → 2+ transition has been studied in the PHFB model. In our earlier work, the reliability of the intrinsic wave functions of96Zr and96Mo isotopes has been established by obtaining an overall agreement between a number of theoretically calculated spectroscopic properties as well as half-lives of 2vββ decay for 0+ → 0+ transition and the available experimental data. In the present work, the half-life of 2vββ decay for 0+ ar 2+ transition T12/2v(0+2+) has been calculated using the same set of intrinsic wave functions.
