The low-lying quadrupole collective excitations of Ru and Pd isotopes
Quadrupole excitations of even-even Ru and Pd isotopes are described within
microscopic approach based on the general collective Bohr model which includes
the effect of coupling with the pairing vibrations. The excitation energies and
E2 transition probabilities observed in 104-114Ru and 106-110Pd are reproduced
in the frame of the calculation containing no free parameters.Comment: 11 pages, 18 figures in EPS forma
Collective quadrupole excitations in the 50<Z,N<82 nuclei with the generalized Bohr Hamiltonian
The generalized Bohr Hamiltonian is applied to a description of low-lying
collective excitations in even-even isotopes of Te, Xe, Ba, Ce, Nd and Sm. The
collective potential and inertial functions are determined by means of the
Strutinsky method and the cranking model, respectively. A shell-dependent
parametrization of the Nilsson potential is used. An approximate
particle-number projection is performed in treatment of pairing correlations.
The effect of coupling with the pairing vibrations is taken into account
approximately when determining the inertial functions. The calculation does not
contain any free parameter.Comment: Latex2e source, 20 pages, 14 figures in EPS format, tar gzipped fil
