化学反应CH_4(~1∑,J)+O(~3P_j)+O(1~D_j)→CH_3(~1∑,J′)+O(~3P_j)H+O(~1D_j)H中的量子干涉效应

Quantum interference on the chemical reaction of CH_4(~1∑,J)+O(~3P_j)+O(~1D_j)→CH_3(~1∑,J′)+O(~3P_j)H+O(~1D_j)H

波长为157nm的O2在受激准分子激光器作用下可离解为O(3Pj)和O(1 Dj).为了在理论上研究化学反应CH4(1∑,J)+O(3Pj)+O(1 Dj)→CH3(1∑,J′)+O(3Pj)H+O(1 Dj)H的量子干涉效应,利用一阶含时波恩近似及各向异性相互作用势建立了量子干涉效应模型,讨论了完全干涉和完全非干涉两种情况.

O（3Pj） and O（1Dj） can be formed from the dissociation of 02 at 157 nm by 157 excimer laser. To study theoretically the quantum interference on the chemical reaction of CH4（1∑,J）＋O（3Pj）＋O（1Dj）→CH3（1∑,J＇）＋O（3Pj）H＋O（1Dj）H, a theoretical model based on the time dependent first order Born approximation and taking into account the Lennard-Jones interaction potential is presented The in- terference angle, which measures the degree of the interference, is derived. The cases of both the com- plete interference and non-interference are discussed.
