The low-lying quadrupole collective excitations of Ru and Pd isotopes
摘要
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.
