The Isovector Quadrupole-Quadrupole Interaction Used in Shell Model Calculations with $\Delta N=2$ Excitations

M. S. Fayache, Y. Y. Sharon, L. Zamick

The effect of the ``$B$'' term in the interaction $-\chi Q\cdot Q(1+B\vec{\tau }(1)\cdot \vec{\tau }(2))$, which was previously considered in the $0p$ shell, is now studied in a larger space which…
