    利用三维总位能面方法,对A～80核区的64个原子核作了三轴超形变的存在性研究.经过计算,从中找到了12个原子核可能存在三轴超形变.研究发现,原子核中的中子转动能对三轴超形变的形成起主要作用,中子壳修正对其形成也有一定的影响.

    The three dimensional Total Routhian Surface (TRS) calculations are carried out for 64 nuclei in the 70 ≤ A ≤ 90 region to find triaxial superdeformed nuclei. A total of 12 nuclei are predicted to have triaxial superdeformation in which the neutron rotational energy plays a key role and the neutron shell energy plays additional role in the formation of triaxial superdeformed nuclei.
