Rotational bands and band crossings in neutron rich Pd and Ag nuclei

High-spin states in 107,108Pd and 109Ag were populated via αxn and pxn evaporation following bombardment of an enriched 96Zr target with an 18O beam at energies of 60 and 70 MeV from the Chalk River TASCC facility. In this reaction, over 90% of the fusion cross section populates cadmium nuclei via xn evaporation. The use of a high-efficiency charged-particle detector array was therefore necessary to select the channels of interest. Charged-particle-γ-γ coincidences were recorded with the 8π spectrometer and ALF charged-particle array. Preliminary yrast level-schemes for 107,108Pd and l09Ag will be presented and compared with theoretical predictions and systematics of neighboring nuclei. In 107Pd, for which the analysis is most advanced, the v h11/2 yrast band is observed to spins of 43/2 h, well above the first band crossing at ω=0.45 MeV/h
