Sr+HF体系的动力学研究

应用扩展的LEPS势能面 ,对处于高碰撞能零振动激发 (Ecol=5 4 .18kJ/mol ,ν =0 ,j=0 )和低碰撞能低振动激发 (Ecol=7.5 6kJ/mol ,ν =1,j=0 )两种初始条件下的Sr+HF体系的竞争反应模式、定态分布函数Pν(b)以及反应碰撞能对产物SrF转动取向的影响进行了准经典轨线计算 ,计算结果与实验结果及相关理论符合得很好 ,且能给予实验以合理的动力学解释 . The quasiclassical trajectory method based on the extended LEPS potential energy surface has been employed here to investigate the reaction mechanism and features in the reaction Sr+HF→SrF+H at two reactional conditions (collision energy E c o l=54.18 kJ/mol, ν=0, j=0 and E c o l=7.56 kJ/mol, ν=1, j=0). The dynamical features in the competitive reaction modes are discussed and the stationary distribution function P ν(b) of the product SrF has already been deduced...
