A semimicroscopic description of Isoscalar Giant Multiple Resonances in medium-mass closed-shell nuclei

Abstract

Main properties of isoscalar giant multipole resonances (up to L=3), including L=0,2 overtones, in medium-mass closed-shell nuclei are described within the semimicroscopic particle-hole dispersive optical model. Main properties are characterized by the energy-averaged strength distribution, projected (one-body) transition density, and probabilities of direct one-nucleon decay. Calculation results obtained for the parameters of the mentioned resonances in the 48Ca, 90Zr, and 132Sn nuclei are compared with available experimental data.
