Abstract:

Microscopic structures of the mode-mode couplings between the RPA γ vibrations and the other Kπ=0+ and ±4+ modes, which are incorporated in the fourth-order collective Hamiltonian for anharmonic γ vibrations, are analysed in detail. The conditions of the subshell structure of the Nilsson orbits near the Fermi surface for enhancement of these mode-mode couplings are clarified. It is predicted that the properties of the double γ vibrational states with Kπ=0+ are especially sensitive to the dynamical anharmonicity effects arising from the mode-mode couplings. Numerical examples are presented for 164,166,168Er.
