¹²⁷La转动带及带终止

摘要: 组态相关推转壳模型 Nilsson势研究了 C.M.Parry组最近用 EUROBALL谱仪观测到的 12 7La高自旋态结构 .实验上观测的 12 7La的宇称和辛量子数为 (π,α) =(+,- 1 /2 )的带自旋达到(83/2 ) h.理论计算结果表明该带可能具有组态 π(h11/2 ) 2 ν(h11/2 ) 6.并且几乎达到该带的带终止理论预言值 I=47.5h.该带的形变在 I≤ 40 h内处于正常形变区 (ε2 ≈ 0 .2 2 ,γ≈ 0°) ,随着角动量的增加 γ值逐渐增加 ,直到 γ=60°时带终止. HJ4/9The configuration dependent shell correction approach with cranked Nilsson potential is employed for explaining the experimental high spin spectra in 127 La.
