Abstract
Twelve known low-lying positive parity levels in /sup 105/Pd up to 962 keV excitation energy were investigated by measuring, in singles mode, with a high resolution 57 cm/sup 3/Ge(Li) detector, the yields and angular anisotropies of the deexcitation ..gamma.. rays following Coulomb excitation with 2 to 4 MeV protons. Out of the seven of these levels which have been populated for the first time through Coulomb excitation with protons, the 696.2 keV level is proposed to be Coulomb excited for the first time. Level energies, the branching ratios, the multipole mixing ratios, B(E2) and B(M1) transition probabilities, and half-lives were deduced. The angular distributions support (5/2)/sup +/, (3/2)/sup +/, (7/2)/sup +/, (5/2)/sup +/, and (3/2)/sup +/ spin-parity assignments, for the 560.6, 673.2, 696.2, 781.8, and 961.9 keV levels, respectively. The present results have been discussed in view of the existing experimental data, as well as in terms of various core-particle coupling models.
