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

L. Zamick, Y. Y. Sharon, A. Escuderos, T. Hoang, S. J. Q. Robinson
It is first noted that as we go up in angular momentum of a yrast sequence in an even-even nuceus there are increasing deviaitions between the shell model and the collective rotational and vibrational models as far sa B(E2)'s and staic quadruple moments (Q) are concerned. But the main theme of this work is that there are often dramtic changes in Q as we go up in J which are not so striking if one looks only at B(E2)s. We comapre B(E2)'s and Q in the Shell, rotational and vibrational models for ^{44} Ti and ^{48} Cr. In ^{96} Cd and ^{92} Pd we compare shell model values these quantities using 2 different interactions,jj44b and JUN45.
