对称性对四体系统结构和内部运动的影响

The Effect of Symmetry on Structures And Internal Motions of a 4-Body System

文中用谐振子乘积基展开法求解了四体系统的Ｓｃｈｒｄｉｎｇｅｒ方程．通过分析波函数及形状密度函数在多维坐标空间的分布，比较了四体全对称０＋态，四体金对称０－态和四体全反对称０＋态，四体全反对称０－态的结构和内部运动的差异；讨论了对称性的影响．

The Schrodinger equation of a 4-body model system has been solved by using harmonic oscillator product states. The distribution of the wave functions and the shape-density functions in the multi-dimensional coordinate space has been investigated. A comparison has been made among the structures and internal motions of the totally symmetric states 0+, 0- and totally antisymmetric states 0+, 0-. The effect of symmetry has been discussed.
