Fragmentation of the 1f neutron-hole strength in89Zr and91Mo

Abstract
The fragmentation of the neutron-hole 1f7/2 and 1f5/2 states in the nuclei 89Zr and 91Mo is calculated within the quasiparticle-phonon model. The interaction of the hole subshells with the 'quasiparticle-plus-phonon' and 'quasiparticle-plus-two-phonon' states is taken into account. The results of the calculation are compared with experimental data for one-nucleon transfer reactions.
