Properties of charge-exchange giant spin-dipole resonances in medium-heavy closed-shell parent nuclei: a semimicroscopic description

Abstract

The semimicroscopic particle-hole dispersive optical model is adapted for a description of main properties of charge-exchange giant spin-multipole resonances in medium-heavy closed-shell parent nuclei. The adapted model is implemented to evaluating the strength functions, transition densities, and branching ratios of direct one-nucleon decay for charge-exchange giant spin-dipole resonances in the 48Ca, 90Zr, 132Sn, and 208Pb parent nuclei. Some of calculation results are compared with available experimental data.
