Title: Universal Anharmonic Vibrator Description of Quasiband Structures in Collective Even-Even and Odd-{ital A} Nuclei

Abstract

It is found that energy correlations within the bands of the good rotor odd-A nuclei are well described by an anharmonic vibrator formula, which indicates an unexpected constancy of the moment of inertia. Based on a large collection of quasibands in all collective even-even and odd-A nuclei, an empirical recurrence relation is proposed which allows one to calculate the excitation energies of any band starting from its lowest two. This simple two-parameter formula can be reduced approximately to that of a second order anharmonic vibrator. {copyright} {ital 1997} {ital The American Physical Society}
