Gamma vibrations and the structure of the nuclear fermi surface

The correlated ground state of deformed heavy nuclei is examined with relation to the Kπ=2+ excited states predicted by the Quasi Particle Random Phase Approximation. Both the schematic and the nonschematic treatments of the residual interaction are considered. The quasi particle density distributio...
