碰撞能量对反应 Sr＋ HF转动取向的影响

摘要

The trajectory calculations of the reaction Sr＋ HF on the extended London-Eyring-Polanyi-Sato (LEPS) potential energy surface have been carried out to study the dependence of product rotational alignment on the collision energies. The calculated results for the reaction of Sr＋ HF were compared with the predictions from the constrained product orbital angular momentum model. The final rotational angular momentum was found to be perpendicularly polarized with respect to the reagents′ relative velocity vector. The higher the collision energies are the more anisotropic is the distribution of the product rotational angular momentum vector.%在推广 LEPS势能面上，用经典轨线方法，研究了反应碰撞能量对反应 Sr＋ HF的转动取向的影响 .计算结果与产物轨道角动量模型进行比较 .计算结果表明，随着碰撞能量的增加，产物转动取向越强烈 .
