Few-Quasiparticle Components of Nuclear States at High Excitation Energies

Abstract

The distribution of strength of the one-quasiparticle and one-phonon states over more complex configurations is studied within the quasiparticle-phonon nuclear model. The values of the Eλ and MI-strength functions are calculated in the region of the neutron binding energy Bn. The position and location regions of the giant EI, E2 and MI-resonances are determined. The calculated curves are compared with the photoabsorption cross sections measured experimentally. The fragmentation of the deep hole state 1g 9/2 in the Sn isotopes is discussed. The results of calculating the s-, p- and d-wave neutron strength functions and the giant resonances of higher multipolarity in deformed nuclei are presented.
