A=100区奇奇核旋称反转

利用两准粒子加轴对称转子模型,对A=100质量区两个奇奇核¹⁰²Rh和^{9 8}Rh的旋称反转进行了研究.结果表明,在A=160,130,80三个质量区奇奇核的计算中 已得到证实的、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.这暗示在不同质量区奇奇核可能存在一种普遍的旋称 反转机制. 关键词： 奇奇核 旋称反转 两准粒子加轴对称转子模型

Signature inversion in odd-odd nuclei in the mass region A=100

With the model of an axially symmetric rotor plus two quasi-particles, the signature inversion (SI) in two odd-odd nuclei ¹⁰²Rh and ⁹⁸Rh in the mass region A=100 is studied. The calculated result shows that the possible SI mechanism, which has been confirmed by the calculation of odd-od d nuclei in the A=160 and A=80 regions (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. This seems to indicate that there mi ght be a universal mechanism of SI in odd-odd nuclei for different mass regions.
