摘要
In order to study the collisional quantum interference(CQI)on rotational energy transfer in atom-diatomsystem,we have studied the relation of the integral interference angle and differential interference angle in Na+Na_2(A^1Σ_u^+,v=8～b^3Π_(Ou),v=14)collision system.In this paper,based on the first-Born approximation of time-dependentperturbation theory and taking into accounts the anisotropic effect of Lennard-Jones interaction potentials,we present a theoretical model of collisional quantum interference in intramolecular rotational energy transfer,and arelationship between differential and integral interference angles.
In order to study the collisional quantum interference （CQI） on rotational energy transfer in atom-diatom system, we have studied the relation of the integral interference angle and differential interference angle in Naq-Na2 （A1 ∑u^＋,v=8-b^3∏0u,v=14） collision system. In this paper, based on the first-Born approximation of timedependent perturbation theory and taking into accounts the anisotropic effect of Lennard-Jones interaction potentials, we present a theoretical model of collisional quantum interference in intramolecular rotational energy transfer, and a relationship between differential and integral interference angles.
