Projected shell model study of yrast bands in even-even 100–118Pd isotopes
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.
