概要	Low-lying states for doubly-odd nuclei around mass 130 are systematically investigated using a pair-truncated shell model. In this model the collective nucleon pairs with angular momenta zero and two are its basic ingredients for even-even nuclei. Additional unpaired neutron and proton are added to the even-even core for a description of doubly-odd nuclei. The effective interactions consist of single-particle energies and monopole and quadrupole pairing plus quadrupole-quadrupole interactions. Energy levels of the low-lying states for doubly-odd nuclei, 132Cs, 130Cs, 134La and 132La, are reproduced very well along with the electromagnetic transitions. The analysis of the wave functions reveals new band structure, 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.
