两准粒子加三轴形变转子模型

摘要: 将两准粒子加轴对称转子模型扩展到三轴形变, 对奇奇核102Rh的旋称反转进行了研究和分析, 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, 三轴形变可以明显地改进能谱的振荡特性.
The model of an axially symmetric rotor plus two quasiparticles for the Signature Inversion (SI) in oddodd nuclei is generalized to the triaxial deformation. The calculation of the odd  odd nucleus 102Rh 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 vibration property of the rotational spectra remarkably.
