Abstract:Quadrupole excitations of even-even Ru and Pd isotopes are described within a 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. Particularly interesting are 104Ru and 106–110Pd where good agreement to very rich information based on Coulomb excitation experiments is achieved.
