Equilibrium deformations of rare-earth nuclei with quadrupole-plus-pairing interactions in a large configuration space

The equilibrium deformations of nuclei in the rare-earth region are studied with the self-consistent quadrupole-plus-pairing interaction model by considering all the nucleons in the nucleus explicitly. It is shown that similar results can be obtained by performing calculations with or without the assumption of an inert core. The only difference is in the strengths of the quadrupole and pairing interactions to be used in the respective calculations. The experimental static quadrupole moments and the B(E2) values are reproduced correctly by performing calculations with bare nucleon charges for all the nucleons.
