摘要

【正】 The alignment of the angular momenta in single-particle energy levels is studied based on a ro-taring two-center shell model for heavy-nucleus ²³⁸U.It is found that large deformation of the nucleusfavours the alignment and a complete alignment of the angular momenta occurs only at large deformationand high cranked frequency.Meanwhile,it is shown that the shell correction energy is mainly determinedby the deformation of the nucleus and slightly varies with the total spin except that the total spin is largerthan 80（?）.It is also found that the two valleys of the potential energy surface become shaUow and finallydisappear with the increase of total spin.
