| Abstract: | We have studied the effective charge and interaction in the (sd) shell with the Bonn-Jülich and Paris potentials. Incorporating essentially all the low-energy correlations of known importance, we find that the former potential gives quite a good account of the data when allowance is made for the effect of low-lying particle-hole states. The Paris potential gives somewhat less core polarization and a less attractive bare T=0 spectrum due to weaker T=0 matrix elements. |
