Driving Effects of the h_11/2 Intruder Orbitals in Odd-N Pd-Isotopes

The deformations of the nuclei in the transitional region are closely related to the orbitals occupied by the quasiparticles. The driving effects of the h_11/2 intruder orbitals in ⁹⁹Pd, ¹⁰¹Pd and ¹⁰³Pd were studied in the framework of the cranked shell model. Based on the total-Routhian-surface (TRS) calculations, the h_11/2 intruder orbitals might polarize the cores of ⁹⁹Pd, ¹⁰¹Pd and 103Pd to a small, but rigid quadrupole deformation,and thus collective rotational motion would develop. The aspects for the research on the high spin states of near the drip-line nuclei in A≈ 210 region as well as our future research work are also briefly reviewed.
