双奇核^(170)Ta的转动带结构

Band Structure in Doubly Odd ^(170)Ta

用能量为105MeV 的^(16)O束流,通过^(159)Tb(^(16)O,5nγ)^(170)Ta 反应研究了^(170)Ta的高自旋态,观察到^(170)Ta 的3个转动带,其中一个耦合带和一个半退耦带中的非优先ΔI=2转动系列是由本工作发现的.文中还讨论了这些转动带可能的准粒子组态.

High spin states in ^(170)Ta have been studied via ^(159)Tb (^(16)O,5nγ)^(170)Ta reaction at 105 MeV.Three rotational bands are observed,among which one coupled band and an unfavored ΔI=2 E2 squence are newly found in this work.The possible quasiparticle configurations of these bands are discussed.
