摘要：
A crossed-beam study of the reaction CH4+ (CH 4,CH3)CH5+ was carried out in the collision energy range 0.6-2.3 eV. Three distinct patterns were observed, which may be interpreted in terms of three competing mechanisms for CH 5+ formation: proton stripping, H-atom pickup, and intermediate complex decomposition. The existence of a C2H 8+ intermediate, stable towards dissociation, is suggested by the results. The relative weights of the three mechanisms were estimated as a function of collision energy. © 1990 American Institute of Physics.
