Nuclear Collective Motion and the Effective Two-Body Potential

Elliott's Q-Q interaction and the other a restoring, term. It is shown that the interaction ca uses nuclear rotational levels and the moment of inertia is about I rig/3 in the case of typical nuclear defomation. Our formalism is the dynamical Hartree method and all results are derived in two-dimensional space. ) and Bethe 3 ). Their results indicate that the nucleus may be approximately described in terms of independently moving particles, in spite of the strong correlations between the constituent particles. We suppose that many features of the nucleus should be understood in the light of the above picture. One of the striking features in low energy nuclear phenomena is the appearance of collective motions. Such nuclear collective motions should be understood on the basis of the independent particle picture, adding another correlations which are lacking in the independent particle picture. As to the above correlations to be added, however, we know little at present, an example of which being the residual interaction appearing in Brueckner's theory. But it will be difficult to show that this residual interaction is the origin of nuclear
