In this paper, we analyse the classifications of critical points on PES with differential dynamics methods, point out that there are only three types of critical points: attracors, repelants and saddle points; and obtain the conditions of PES topological structures losing their stability (TSLS). Finally, we obtain the conditions of TSLS and bifurcations of reactive paths on A+B2 reactive potential energy surface.

Key words: Potential energy surface;Topological structures losing stability;Bifurcation of reactive paths
