摘　　要：应用包含单极对力及四极对力的粒子数守恒方法对A～ 190区的奇奇核194 Tl和奇A核193Tl中的全同带进行了研究 .结果发现堵塞效应对全同带的形成及转动惯量随角频率变化的微观机制都起着非常重要的作用 .同时文中对194 Tl的 6条超形变转动带相对于193Tl(1)的角动量顺排i(ω)的量子化也做了研究 .The microscopic mechanism of the identical bands in odd-odd nucleus 194Tl and its neighbor odd-A nucleus 193Tl are investigated using the particle-number conserving (PNC) method with monopole and quadrupole pairing interaction. It is found that the blocking effect plays an important role in the variation in moments of inertia (J (1) and J (2) ) with rotational frequency for the SD bands and identical bands. And the angular momentum alignment i(ω) of the six SD bands in 194Tl relative to the 193Tl(1) also is discussed.
