The high spin states of the 105,106Pd have been studied via the fusion-evaporation reactions 96Zr(13C, 3nγ)106Pd and 96Zr(13C, 4nγ)105Pd. The Zr beam with energies 40 MeV and 50 MeV respectively, was provided from the Tandem accelerator at IKP, University of Cologne. The gamma rays were detected with HORUS spectrometer. The preliminary results from the data analysis will be presented. Previous experiments on Pd and the present results have shown that the majority of states populated by (HI, xn) reactions in Pd nuclei are members of decoupled collective bands built on quasineutron states. These nuclei provide an unusually simple and complete illustration of the relation between particle and collective motion in slightly deformed nuclei. These experiments provide ample evidence that the yrast states populated in (HI, xn) reactions are in good agreement with a slightly deformed-rotor description of these nuclei.
