摘要:
CO(A1Π,v=0-e3Σ-v=1)-HCl体系中的碰撞诱导量子干涉效应已经在静态池中被观测到,且测量到的干涉相位角分别是101°(J=12)和110°(J=13),此结果实际上是对各种可能碰撞参数和碰撞能量的加权平均.为探知被积分效应掩盖的动力学信息,分析微分干涉相位角对于碰撞参数(b)和碰撞相对速度(v)的依赖关系.结果表明,对物理上有意义的bv,CO-HCl体系的微分干涉相位角分布在93°~116°范围,都是大于90°的钝角,说明不存在正干涉和负干涉相互抵消的问题,平均效应不严重.
Abstract:
That collision induced quantum interference effects was demonstrated in gas cell experiments within CO(A1Π,v=0~e3Σ-v=1)-HCl system.The interference phase angles were measured to be 101±3° and 110±5° for CO rotation quantum number J=12 and J=13, respectively,where the interference angle represents some“average”effect for collisions with different impact parameter b and collision velocity v. In order to understand the dynamics information covered by the average effects,the relationship of differential interference phase angle θDST on b and v was analyzed.The results indicate that within reasonable scope of b and v,θDST is in the range of 93°~116° for the system CO-HCl.The fact that θDST is always greater than 90° shows that there is no cancellation between positive and negative interferences and the “levelling effect” is not serious.
