Importance of static quadrupole moments for determining collective aspects of nuclear structure: N=Z calculations with four and eight valence particles

Abstract

In this work we look at the low lying nuclear structure of several N=Z nuclei residing between the doubly magic nucei ^{40} Ca and ^{100} Sn. Using large shell model codes we calculate and discuus the systematics of enegies. We show energy levels, B(E2)'s, static quadrupule moments and g factors. In all cases we compare the results of 2 different interactions which yield significanly different occupation numbers. We compare with the simplest versions of the rotational and vibrational models. By examinnig B(E2)'s and static quadrupole moments we make associations with collective models find that in the model space here considered ,{}^{88} Ru is oblate . The quadruple moment of ^{92} Pd is very small consistent with the vibrational model.
