We present a study of the collective quadrupole excitations in some medium heavy transitional nuclei, namely 102Zr, 104Mo, 110Ru, 110Pd, 124Xe and 126Ba, within the frame of a self-consistent model with the Skyrme SIII forces. The full five-dimensional collective dynamics is treated through the Bohr Hamiltonian with mass parameters and moments of inertia calculated microscopically. We discuss consequences stemming from the approximate inclusion of Thouless–Valatin corrections as well as effects of various shapes of the pairing interactions (G force, small delta, Greek and density dependent small delta, Greek forces).
