利用全Routhian面计算方法研究了NO同位素的形变和排列性质。发现在低激发能下,这些核中的正常形变态和超形变态可以共存。在缺中子的NO同位素中,超形变的形状甚至可以成为基态。此外,我们绘制了NO同位素的运动学惯性矩,这些惯性矩遵循非常好的实验数据。值得注意的是,随着旋转频率的增加,对齐发展?= 0.2?0.3兆电子伏计算结果表明,vj 15/2轨道的占据对NO同位素的排列起着重要的作用.
Total-Routhian-Surface calculations have been performed to investigate the deformation and alignment properties of the No isotopes. It is found that normal deformed and superdeformed states in these nuclei can coexist at low excitation energies. In neutron-deficient No isotopes, the superdeformed shapes can even become the ground states. Moreover, we plotted the kinematic moments of inertia of the No isotopes, which follow very nicely available experimental data. It is noted that, as the rotational frequency increases, alignments develop at ?? = 0.2?0.3 MeV. Our calculations show that the occupation of the vj15/2 orbital plays an important role in the alignments of the No isotopes.
