INTRINSIC VS LABORATORY FRAME DESCRIPTION OF THE DEFORMED NUCLEUS CR-48

The collective yrast band of the nucleus Cr-48 is Studied using the sp herical shell model and the Hartree-Fock-Bogoliubov (HFB) method. Both approaches produce basically the same axially symmetric intrinsic sta te up to the-accurately reproduced-observed backbending. Agreement bet ween both calculations extends to most observables. The only significa nt discrepancy comes from the static moments of inertia and can be att ributed to the need of a more refined treatment of pairing correlation s in the HFB calculation.
