超形变带的唯象分析

Phenomenological Description of Superdeformed Bands

利用量子代数两种不同的表示和原子核软度系数的定义 ,给出了描述正常形变核和超形变核两个不同的转动谱公式 .对A～ 1 90 ,1 50区超形变转动带的分析结果表明 ,超形变带能谱公式不仅可以相当精确地描述γ跃迁能谱 ,而且可以复现动力学转动惯量的“返转”(turnover)

Two different rotational formulae for description of normal deformed and superdeformed nuclei are submitted by the definition of the softness and by two different representations of quantum algebra.With SD formula,near 80 SD bands in A～ 190 and 150 regions are calculated.The results show that the E2γ ray energies are fitted in high quality,and the phenomena of the turnover in dynamical moment of inertia can be also reproduced well.
