英文摘要: To interpret theoretically the abnormal phenomenon in the experiment of collision-induced rotational energy transfer of CO (A (1)Pi, v = 3) with He by Sun et al., the time dependent first order Born approximation, and the long-range interaction potentials and "straight-line" trajectory approximation are taken into account. A theoretical model of quantum interference of II-state diatomic molecules, which originates from the difference between the two Lambda-related collision potential energy surfaces, is presented. The abnormal phenomenon of sigma(DeltaJ=0)(s-->s)<σ(s-->s)(&UDelta;J=+/-1) for He is also interpreted successfully. At first the theoretical development of collision-induced quantum interference on rotational energy transfer is reported; then a theoretical model of quantum interference of II-state diatomic molecules, which originates from the difference between the two A-related collision potential energy surfaces, is presented; in the end the results have been discussed and concluded.
