Popis:	Collision-induced quantum interference (CQI) was demonstrated within energy transfer of CO(A 1 Π, v = 0–e 3 Σ − , v = 1)–He in a gas cell, where interference angle θ ST represents some ‘average’ effect for collisions with different impact parameter b and collision velocity v . By using quantum scattering theory, a method of calculating differential interference angle θ ST D , which is related to b and v , was presented. θ ST D was calculated for CO(A/e)–He with all v and b values that are physically significant. Results obtained for θ ST D are in the range of 30–70°, which imply there is no problem of cancellation between positive and negative interferences and ‘average effect’ is not serious.
