76Se三声子态成员的候选者

通过⁷⁶Br (T_1/2=16.2h)β⁺/EC衰变方法得到⁷⁶Br衰变纲图, 并确认了Muller等通过核反应⁷⁶Se(p, p′)方法发现⁷⁶Se能级纲图中1791.31keV能级. 不过, Muller等当时并没有指出该条能级的自旋和宇称, 以及应该属于哪一个声子态的成员. 经过分析我们认为1791.31keV能级可以作为⁷⁶Se三声子态的一个候选成员. 此外, 为了研究这个介于强形变和球形核之间的过渡区核的形变, 对它的正宇称态进行了采用推转壳模型形式的总转动能面计算.

Further research on high-spin structure in 161Lu

The two-dimensional total routhian surface (TRS) calculations were performed to probe into the triaxial superdeformed characteristics of a strongly populated band X2 in ¹⁶¹Lu. This band was identified as a triaxial superdeformed band by using our TRS method. We also got its formation mechanics, i.e. the neutron-shell correction energy plays a crucial role, while the rotating energy and the deformation-driving effect of high j intruder orbit i _13/2 also play an additional role.

Possible existence of triaxial superdeformation in 172,174,176W

Two-dimensional total routhian surface (TRS) calculations are carried out to determine the triaxial superdeformation (TSD) of the even-even nucleus 174W, and the result indicates that TSD state exists with deformation parameters ε2=0.42 and γ=34.7°. In the same way, the total routhian surfaces for the nuclei 172,176W are also calculated. It shows that the neutron shell correction energy plays a key role in the formation of TSD nuclei 172,174,176W, while the high j intruder orbitals and rotational energy are also crucial in the formation mechanism.     

Alignments in the nobelium isotopes

Total-Routhian-Surface calculations have been performed to investigate the deformation and align-ment 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, align-ments develop at hω=0.2-0.3 MeV. Our calculations show that the occupation of the vj<,15/2> orbital plays an important role in the alignments of the No isotopes.
