Application of realistic effective interactions to the structure of the Zrisotopes - art. no. 064318

We calculate the low-lying spectra of the zirconium isotopes (Z=40) with ne utron numbers from N=52 to N=60 using the 1p(1/2)0g(9/2) proton and 2s1d0g( 7/2)0h(11/2) neutron subshells to define the model space. Effective proton- proton, neutron-neutron, and proton-neutron interactions have been derived using Sr-88 as closed core and employing perturbative many-body techniques. The starting point is the nucleon-nucleon potential derived from modern me son exchange models. The comprehensive shell-model calculation performed in this work provides a qualitative reproduction of essential properties such as the subshell closures in Zr-96 and Zr-98.
