Abstract

The empirical effective proton-neutron interaction was investigated in the singly closed shell region. It was found that the quadrupole component of the effective interaction is about twice as strong in this region as in the doubly magic one. The presence of the additional quadrupole-quadrupole interaction was explained as the first experimental evidence for the existence of the polarization interaction predicted by Bohr and Mottelson as a second order consequence of the particle-vibration coupling. It was shown that the renormalization of higher order multipole coefficients is also necessary to take into account all effects of the particle-vibration coupling. We pointed out that this renormalization can be approximated by lengthening the range of the effective interaction.
