摘　　要：利用三轴粒子－转子模型研究了Ａ～１９０区奇Ａ核超形变全同带，采用标准的ＢＣＳ方法处理对关联，分析了（１９１Ａｕ，１９１Ｈｇ（ｂ１）），（１９１Ｈｇ（ｂ２），１９３Ｈｇ（ｂ２））和（１９１Ｈｇ（ｂ３），１９３Ｈｇ（ｂ３））三对全同带，指出特定轨道的填充是造成全同带的重要原因．Identical bands of odd-A superdeformed nuclei in the A￣190 mass region have been investigated using triaxial-particle-rotor model within the framework of the BCS pairing correlation. Three pairs of identical bands (191Au, 191Hg(b1)), (191Hg(b2),193Hg(b2)), and (191Hg(b3), 193Hg(b3)) are analyzed. It is pointed out that the identity in the γ-transition energies in these bands may be the result of the occupation of some special orbitals.
