We perform shell-model calculations for nuclei below Sn-100, focusing attention on the two N = Z nuclei, Cd-96 and Pd-92, the latter having recently been the subject of great experimental and theoretical interest. We consider nuclei for which the (0)g(9/2) orbit plays a dominant role and employ a realistic low-momentum two-body effective interaction derived from the CD-Bonn nucleon-nucleon potential. This implies that no phenomenological input enters our effective Hamiltonian. The calculated results for Pd-92 are in very good agreement with the available experimental data, which gives us confidence in our predictions for Cd-96. An analysis of the wave functions of both Cd-96 and Pd-92 is performed to investigate the role of the isoscalar spin-aligned coupling.

Abstract
We perform shell-model calculations for nuclei below Sn-100, focusing attention on the two N = Z nuclei, Cd-96 and Pd-92, the latter having recently been the subject of great experimental and theoretical interest. We consider nuclei for which the (0)g(9/2) orbit plays a dominant role and employ a realistic low-momentum two-body effective interaction derived from the CD-Bonn nucleon-nucleon potential. This implies that no phenomenological input enters our effective Hamiltonian. The calculated results for Pd-92 are in very good agreement with the available experimental data, which gives us confidence in our predictions for Cd-96. An analysis of the wave functions of both Cd-96 and Pd-92 is performed to investigate the role of the isoscalar spin-aligned coupling.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
