回弯的简单公式

A Simple Formula for Backbending

用吴-曾公式描述基带,用常转动惯量公式描述超带,且引入一个唯象的带间相互作用将两个带混合,即可得到对大多数原子核晕带和次晕带较为理想的描述,还可重现转动惯量的回弯。对公式中的参数做进一步的分析后,可获得核的基态转动惯量与刚体转动惯量等信息。

Using Wu-Zeng formula to characterize g-band, Bohr-Mottelson formula to describe sband, and introducing a tentative interband interaction, a better description for the yrast, and yrare-band of the most even-even well-deformed nuclei is obtained. The backbending of the moment of inertia is also well reproduced in this formalism. By analysing the parameters used here, other information such as the moment of inertia for the ground state can be concluded.
