Equilibrium deformations of heavy nuclei

The equilibrium deformations of nuclei in the rare earth and transition region (146< or =A< or =192) are studied with the self-consistent quadrupole plus pairing interaction model, by considering all the nucleons in the nucleus explicitly in the configuration space of the first seven major oscillator shells for both protons and neutrons. The present results are in agreement with those obtained earlier by assuming an inert core and employing the renormalized strengths for the quadrupole and pairing interactions. The experimental B(E2) values are correctly reproduced by employing bare nucleon changes in large configuration space
