Based on the hybrid solutions to(2+1)-dimensional Kadomtsev–Petviashvili(KP) equation, the motion trajectory of the solutions to KP equation is further studied. We obtain trajectory equation of a single lump before a...
Quasi-classical trajectory(QCT)calculations are reported for the H+LiH(v=0-2,j=0)→Li+H2 reaction on a new ground electronic state global potential energy surface(PES)of the LiH2 system.Reaction probability and integr...
