对于原子-双原子分子的反应散射采用核间距作坐标。经过坐标的质量标度化,坐标旋转及换成超球坐标,则量子反应散射具有与非弹性散射相似的表达式。在此描述下,反应体系自然地、均匀地由反应态转化为产物态,避免了不同排列通道间的坐标变换。 For atomic-diatomic molecular scattering reaction using nuclear spacing as coordinates. After the coordinates of the quality of scaling, coordinate rotation and replaced by hypersphere coordinates, the quantum reaction scattering with inelastic scattering similar expressions. In this description, the reaction system is naturally and uniformly transformed from the reaction state to the product state, avoiding the coordinate transformation between different alignment channels.
