Abstract
The yrast spectra with Jmaxpi = 10+, B(E2) transition probabilities and QJ+ values are calculated for even-even ruthenium isotopes by carrying out variation after projection (VAP) 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 76Sr core. Our calculations describe the shape changes as a function of mass number for ruthenium isotopes and also reveal that both the HFB technique as well as the quadrupole-plus-pairing-quadrupole model of the two-body interaction are fairly reliable in this mass region.Keywords
