Abstract

The semi-microscopic particle-hole dispersive optical model, having unique abilities in describing main properties of various giant resonances in medium-heavy-mass spherical nuclei, is applied to a number of Isoscalar Giant Multipole Resonances in one-closed-shell nuclei 58Ni, 120Sn, and 142Nd. Some of the calculation results are compared with respective experimental data, including those obtained just recently. Special attention is paid to a comparison of calculated isoscalar multipole strength functions with the respective experimental strength distributions in a wide excitation-energy interval.
