英文摘要:
The ionization of CO with metastable He(2(3)S) was studied using the method of molecular beam. The branching ratio 1:2.2 of the products CO+ (A) to CO+ (B) was obtained. This is attributed to the activity difference between 1 pi and 4 sigma orbitals of CO(X). Owing to the correlativity existing between the nascent vibrational distribution of the CO+ (A) and the corresponding Franck-Condon factors, the process occurs through a vertical transition. The rotational temperatures of the nascent CO+ (B, v' = 0) and CO+ (A, v' = 0, 1, 2, 3) are lower than that of the reactant. This phenomenon is attributed to the linear configuration of the (He-CO)(+) complex.
