Abstract As is well-known, a central problem of nuclear physics is to understand the nature of the isolated nucleon-nucleon inter- actions and to explain the properties of complex nuclei in terms The description of nuclear systems. of these nuclear forces. can be attempted in a fundamental or microscopic sense by ic itly accounting for the motion of each nucleon. This approach is generally quite complex and closed-form analytic expression is seldom available. Alternately, one might develop relevant macroscopic or many-body concepts, models, and parameters in terms of which a satisfactory treatment of complex nuclei could be sought. In atomic structure the inter-electron force is sufficiently weak (12) compared to the central electron-nucleus attraction that the energy levels of many electron atoms can be calculated quite well in first order perturbation theory starting from a self-consistent central field. In nuclear structure it is well established experimentally through the success of the shell model that a central field also dominates the behaviour of nuclei although it is also clear from experiment that there is a very much greater mixing of configurations in nuclei than in atoms(1). The simplicity of the central field approximation is so appealing and the empirical evidence for its features are so convincing that we suppose there to be a correspondence between the uhell model wave functions in some fairly pure configuration and the low- lying states of nuclei. |
