Spectroscopic factors of magic and semimagic nuclei within the selfconsistent theory of finite Fermi systems
Abstract
A scheme is presented to find singleparticle spectroscopic factors (SF) of magic and semimagic nuclei within the selfconsistent theory of finite Fermi systems (TFFS). In addition to the energy dependence of the mass operator Σ induced by the surfacephonon coupling effects which are commonly considered in this problem, the involume energy dependence of the operator Σ inherent in the selfconsistent TFFS is also taken into account. This dependence arises due to the effect of highlying particlehole excitations and persists in nuclear matter. The selfconsistent basis of the energy density functional method by Fayans et al. is used. Both the surface and involume contributions to the SFs turned out to be of comparable magnitude. The results for magic ^{40,48}Ca and ^{208}Pb nuclei and semimagic lead isotopes are presented.
