Eine qualitative Diskussion der kollektiven potentiellen Energie im Quasispinmodell

The collective potential-energy-surface is calculated for a simple nuclear model consisting of a closed core and onej-shell. This shell can be filled up by one sort of nucleons (protons or neutrons). The residual force acting between nucleons consists of a pairing- and a quadrupol-force. In the quasi-spin-formalism, proposed by A. K.Kerman, the parameters of the collective potential energy are calculated and the collective features of even-even nuclei were discussed qualitatively.
