SELFCONSISTENT SEMICLASSICAL CALCULATION WITH EXTENDED SKYRME FORCES AND THE PROPERTIES OF ISOVECTOR GIANT RESONANCES

Li G, Xu G

Abstract

The properties of isovector giant resonances are discussed with the help of the nuclear ground state density profiles obtained from self consiotent semi-classical calculation. Both the component with △T_■=0 and the components with △T_■=±1 are considered. The isospin properties of the giant resonances are thereby studied. The results are in good agreement with HF + RPA calculation and experimental evidences.
