Properties of isoscalar giant multipole resonances in medium-heavy closed-shell nuclei: A semimicroscopic description

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 48 Ca, 90 Zr, and 132 Sn nuclei are compared with available experimental data.
