Systematics of nuclear surface vibrations in deformed nuclei

The low-energy spectra and electromagnetic transitions for a series of heavy deformed nuclei are analyzed in the framework of the pseudo-SU(3) model. A realistic Hamiltonian with proton and neutron single particle energies, monopole pairing interaction, in addition to the quadrupole-quadrupole term, is used. The strengths of the interactions are fixed with values from systematics. The effect of the single-particle energies on the overall spectra and electromagnetic transition is analyzed. (author)
