Charge-Exchange Resonances in Deformed Nuclei

Abstract

In recent years the Gamow-Teller (GT) and spin-dipole charge-exchange resonances have widely been studied experimentally and theoretically in atomic nuclei including the deformed ones [1]. The study of the GT resonance is associated with the calculation of β-strength functions. The first calculations of the GT resonances in deformed nuclei have been performed in refs. [2,3] while studying β-decay of the rare-earch nuclei and rubidium isotopes and for some nuclei in the rare-earth and actinide region. The calculations were performed in the random phase approximation (RPA). The above approximation is well fulfilled for the deformed nuclei.
