Abstract
The calculated contribution of core polarization to the effective interaction between two nucleons in a nucleus is shown, for certain potentials, to be much larger in the random-phase approximation than in first-order perturbation theory. Collective quadrupole and (in one case) monopole excitations are responsible for this.Keywords
