Excitation of Low-Lying Collective Bands in Inelastic Hadron Scattering

摘要

We consider the excitation of beta - and octupole bands in permanently deformed nuclei in the framework of the coupled-channel method. Transition densities for the beta - and octupole bands derived from the ground-state density and satisfying, respectively, the conditions of particle conservation and translational invariance are presented. Transition potentials derived from optical-model potentials along similar lines are used in the coupled-channel analysis of inelastic hadron scattering fom beta - and octupole bands in deformed nuclei. The coupling of giant-resonance modes into these low-lying bands manifesting themselves in additional terms to the transition densities is discussed. (ERA citation 08:039684)
