Abstract

The projected shell model (PSM) study of ^100–118Pd nuclei is carried out. The reliability of the ground-state wave functions is checked by reproducing yrast spectra and electromagnetic properties. The results of calculations indicate that the observed deformation systematics in ^100–118Pd isotopes depends on the increase of occupation probability of (1h _{11/2 ν} ) orbit and the deformation producing tendency of n-p interaction operating between Spin Orbit Partner (SOP) orbits (d _5/2)_π−(d _3/2) _ν and (g _9/2)_π−(g _7/2) _ν . Beside this, the results on band diagrams show that the yrast spectra in Pd isotopes do not arise from a single intrinsic state only but also from multi-quasiparticle states.
