摘　　要：为了研究CO(A′∏,v=3)和He碰撞体系由于∏态Λ分裂引起的量子干涉现象的微分干涉角和相对速度的关系,考虑一级波恩近似,各向异性相作用势和直线轨迹近似,对微分干涉角进行了推导,利用得出的公式,研究了微分干涉角和相对速度的关系.As a theoretical study of the relationship between the differential interference angle and velocity of collision quantum interference effect from the ∧ split of П state diatom, based on the first born approximation and considering anisotropic Lennard- Jones interaction and ＂straight- line＂ trajectory approximation , a formula of the differential interference angle is scribed. Using the formula, the relationship of the differential interference angle and velocity is studied.
