Collective hamiltonian derived from the pairing-plus-quadrupole model

The microscopic collective hamiltonian for the axial quadrupole vibrations was derived from the QQ + PP model. The generator coordinate method and the generalized gaussian overlap approximation were used. The results were compared with the cranking estimates. The zero-point correction to the potential energy was found important. The mass parameters for the full two-body hamiltonian are nearly the same as for the mean-field approximation to that hamiltonian. 15 refs., 5 figs. (author)
