超变形核转动惯量变化规律的微观理论和唯象分析

The long standing open problem of the microscopic mechanism of "identical bands" in superdeformed and normally deformed nuclei is clarified by using the particle-number conserving method. The reason why the moments of inertia of most multiquasiparticle bands are quite different from those of ground-state bands in neghboring even-even nuclei is also demonstrated, where the blocking effect plays a crucial role.

按照我们建立的从带内跃迁能量来确定转动带角动量的几种方案，对超变形带进行系统分析，给出可靠的自旋指定，并提取超变形带转动惯量的变化规律（随角动量、费米能、内部激发、奇偶差）。用粒子数守恒方法（采用各种对力形式）进行理论分析，从内部态结构来阐明从实验提取的唯象规律，找出超变形核与正常形变核不同的特点，研究发现的新课题。
