Abstract

The spectroscopic properties of the doubly closed-subshell nucleus 96Zr have been investigated within the framework of the RPA and QRPA. For the residual interaction a Landau-Migdal density-dependent zero-range force has been used in the particle-hole and particle-particle channels. The full level scheme of 96Zr up to 5 MeV has been reproduced, including both the predominantly collective levels and the more pure particle-hole and particle-particle states. It is shown that the state-dependent pairing gaps, which result from a density-dependent δ-interaction as well as the inclusion of the particle-particle interaction, are essential in the description of the level structure of this nucleus.
