摘要
利用准三原子近似及半径验的ＬＥＰＳ形式势能面研究了Ｂａ＋ＢｒＣＨ３反应碰撞动力学，得出反应络合物寿命大的１微微秒；反应几率随碰撞能增加缓慢减小，这与分子束实验一致；此外得出产物ＢａＢｒ的振转分布都是非线性惊奇．
Abstract The dynamics of the Ba+BrCH3 reactive callision has been studied by the quasitriatomic approximation and the semi-empirical LEPS potential energy surface. We obtained the lifetime of the complex or reaction collision to be nearly 1 ps. It concluded that the reaction probability decrcases slowly as collision energy increases, it is consistent with the molecular beam experiments. Furthermore, the vibrotahonal state distributions or the BaBr products obtained arc all non-linear surprising.
