Abstract

The yrast spectra, intrinsic quadrupole moments and root mean square radii for each angular momentum state, calculated for 108–112Ru isotopes by carrying out Cranked-Hartree-Fock-Bogoliubov (CHFB) calculations. These calculations have been performed by employing pairing-plus-quadrupole-quadrupole effective interaction operating in a reasonably large valence space outside 76Sr core. The experimentally available spectra upto 10+ is reasonably well reproduced. Our results indicate that there is a possibility for observing backbending phenomenon in 108,110,112ru at spins 12 +, 20+ and 14+, respectively, which remains yet to be confirmed experimentally.
