Quasielastic excitation functions for the 12,13 Cϩ 105,106 Pd systems were measured at near barrier energies. The representations of the fusion barrier distributions derived from the measured cross sections were analyzed by comparison with simplified coupled-channel calculations. The influence of transfer reaction channels can be distinguished from that due to the inelastic excitation. The influence of two-phonon state on the barrier distributions was evaluated.

Level schemes for~~R b and 9~Sr are proposed based on the study of the P decay of S~Kr and 9~Rb, respectively. The samples mexe obtained using on-line mass-separation techniques applied to~3 5U fission products. y-, P-, and x-ray singles spectra, as mell as (y, y} and (P, y} coincidence spectra, mere taken with Ge(Li} and Si(I i} detectors. Internal-conversion coefficients mere determined for several transitions and the half-lives for the first two levels in Gab and 9~Sr mere measured. In viem of the observed parity change between lorn-lying excited states and the ground state in 9~3b the possibility of deformations to explain this level structure is discussed.
