Description

The two-neutrino double-beta decay of 124,126Xe, 128,130Te,130,132Ba and 150Nd isotopes is studied in the Projected Hartree-Fock-Bogoliubov (PHFB) model. Theoretical 2 ν β-β- half-lives of 128,130Te, and 150Nd isotopes, and 2νβ+β+, 2 ν β+EC and 2νECEC for 124,126Xe and 130,132Ba nuclei are presented. Calculated quadrupolar transition probabilities B(E2:0+→2+), static quadrupole moments and g-factors in the parent and daughter nuclei reproduce the experimental information, validating the reliability of the model wave functions. The anticorrelation between nuclear deformation and the nuclear transition matrix element M2ν is confirmed. (orig.)
