双原子分子激发态转动传能量子干涉效应模型

Model of quantum interference effect on rotational energy transfer within diatomic molecules excited states

物质波的干涉是由于微观粒子具有波的特性而产生的干涉现象.对于双原子分子单三重混合态转动传能过程具有波动特性,两个通道间存在量子干涉效应.基于玻恩近似的微扰理论,本文利用各向异性相互作用势和直线轨迹近似给出了包含干涉相位角的干涉表达式,建立了新的量子干涉模型,并讨论了此模型中利用的近似理论.

Microscopic particle exhibit wave properties because of wave-particle duality of quantum me- chanics, numerous examples of quantum interference effect within matter-wave had been discovered. For the singlet-triplet mixed states in diatom molecule, quantum interference present in two transfer roads. The theoretical model of Quantum Interference is described in an atom-diatom system, based on the first-Born approximation of time dependent perturbation theory, taking into account the anisotropic Len- nard-Jones interaction potentials and ＂straight-line＂ trajectory approximation, the approximation condi- tions of the CQI model is discussed.
