E2 transition and QJ+ systematics of even mass palladium nuclei.

Abstract

The yrast spectra with {ital J}{sub max}{sup {pi}}=10{sup +}, {ital B}({ital E}2) transition probabilities, and {ital Q}{sup +}{sub {ital J}} values are calculated for even-even palladium isotopes by carrying out variation-after-projection calculations in conjunction with the Hartree-Fock-Bogoliubov (HFB) ansatz employing a pairing-plus-quadrupole-quadrupole effective interaction operating in a reasonably large valence space outside the {sup 76}Sr core. Our calculations describe the shape changes as a function of mass number for palladium isotopes and also reveal that both the HFB technique and the quadrupole-quadrupole-plus-pairing model of the two-body interaction are fairly reliable in this mass region. {copyright} {ital 1996 The American Physical Society.}
