| 摘 要： | 具有绕z轴的M重对称性和时间反演对称性系统的哈密顿量可以导致自旋宇称效应 ,给出了源于镜面反射对称性的自旋宇称效应的纯量子力学理论 ,并与源于绕z轴二重对称性导致的自旋宇称效应作了比较。结果表明 ,系统具有镜面反射对称性也是导致自旋宇称效应的原因。

| Abstract: | Spin parity effect (SPE)plays an important rule in the study of macroscopical phenomena in quantum tunneling. The Hamiltonian of the system with M th symmetry around z axis and time inverse evolution symmetry can cause the spin parity effect. A pure quantum mechanics theory of SPE based on mirror reflection symmetry is given and compared with SPE caused by second symmetry around z axis. The result shows that the mirror reflection symmetry of the system can also cause SPE. |
