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

The semimicroscopic particle-hole dispersive optical model is adopted for a description of main properties of isoscalar giant multipole resonances (up to L = 3) in medium-heavy closed-shell nuclei. The main properties are characterized by the strength distribution, transition density, and partial and total probabilities of direct one-nucleon decay. The model is implemented to describe characteristics of the mentioned resonances in the Pb-208 nucleus, taken as an example. Calculation results are compared with available experimental data.

Automated summary

The semimicroscopic particle-hole dispersive optical model is used to describe the main properties of isoscalar giant multipole resonances in medium-heavy closed-shell nuclei, focusing on strength distribution, transition density, and probabilities of direct one-nucleon decay. The model is applied to analyze the characteristics of these resonances in the Pb-208 nucleus, and the calculation results are compared with experimental data.
