A=100区奇奇核旋称反转及三轴形变对它的影响

将两准粒子加轴对称转子模型扩展到对A=100质量区两个奇奇核^102Rh和^98Rh的旋称反转的研究后，又在此基础上引入原子核的三轴形变．计算结果表明，可能的旋称反转机制(即：低K空间n—p相互作用和科氏力的相互竞争)，对于A=100质量区奇奇核也是适用的．在引入了三轴形变后与轴对称情形下相比较，明显地改进了能谱的振荡特性。

Signature Inversion in Odd-odd Nuclei in the Mass Region A 100 and the Influence of the Triaxial Shape

The model of an axially symmetric rotor plus two quasi-particles for the Signature Inversion (SI) in odd-odd nuclei is generalized to the calculation of two odd-odd nuclei l02Rh and 98Rh in the mass region A =100. The triaxial deformation is then introduced. The calculation result shows that the possible SI mechanism (i. e. , the competition between the n - p interaction and the coriolis force in low K space) is also appropriate for odd-odd nuclei in the A = 100 region. A triaxial shape can improve the vibrational property of the rotational spectra remarkably.
