摘要：
Low-lying states for doubly-odd nuclei in the mass A similar to 130 region are investigated using a pair-truncated shell model. Energy levels of the low-lying states for doubly-odd nuclei, Cs-132, Cs-130, La-134, and La-132, are reproduced very well along with the electromagnetic transitions. The analysis of the wave functions reveals band structure for doublet bands built on the nu h(11/2)circle times pi h(11/2) configuration, showing various angular-momentum configurations of the unpaired neutron and the unpaired proton, weakly coupled with the quadrupole collective excitations of the even-even part of the nucleus.
