Abstract:

In even-even Zr nuclei, with the neutron number increasing from N=56 on, a steady lowering of the first excited 0+ state is observed. This excited 0+ state has been mainly related to the proton excitation across the Z=40 subshell. Starting from the shell-model matrix element, connecting the (2p1/2)20+ and (1g9/2)20+ configurations in Zr90, we point out that a large reduction in the coupling matrix element is needed to explain the very low 0+ excitation energy at N=58, N=60. This reduction is calculated, starting from the matrix element connecting the spherical valence neutron configuration and a Nilsson model deformed wave function describing the neutron component. © 1988 The American Physical Society.
