Abstract

¹⁵²Dy is the first observed superdeformed nucleus, whose band structure reflects the typical distribution of high j low Ω orbitals of superdeformed nuclei in A~150 mass region. The particle-number conserving treatment of the cranked shell model with monopole and quadrupole paring interactions is adopted to investigate the observed six superdeformed bands in ¹⁵²Dy. The ?[523]7/2 orbital is emphasized for the first time to interpret the microscopic structure of band 2 and 3 of ¹⁵²Dy. A new comprehension is proposed on the basis of ever existing experimental and theoretical results, and the reliability is illustrated by several superdeformed bands of neighboring nuclei.
- superdeformed band,
- momenta of inertia,
- cranked shell model,
- doubly magic ¹⁵²Dy
