Abstract：
Phase transition in odd- Nisotopes ^99,101,103Pd are investigated via the E-GOS (E-Gamma Over Spin) curves, which strongly suggest a structure evolution from vibration to rotation along the yrast lines with increasing spin. Theoretical calculations have been performed for the ground state bands of ^99,101,103Pd in the framework of the cranked shell model (CSM) and the alignment properties observed experimentally are analyzed employing this model. The results show that the phase transition in the ground state bands of ^99,101,103Pd can be interpreted as the valence nucleons start to occupy the g _9/2proton orbitals with increasing spin which would polarize the core to a small, but rigid quadrupole deformation.
