Theory of collective vibrations of even-even spheroidal nuclei

Abstract

A version of the Inglis 11 c:cn.~dng model 11 is presented '/nich describes nuclear shape o~clll.u•ctoJ::f3 without the adiabatic npproximntiono 'Ihe collective frequti.1Cies of a system of particles moving in a time-dependent shell-!::cdel pote11tial are obtained as solutions of a dispej_~sion equ.t:.:c.ion usu8.lly associated with the rando:n !."Lase approximation (l1PA).
