摘要：
The transfer-excitation process in O8++H-2 collisions is studied at high impact energies using an independent event model. The transfer-excitation probability is expressed as a product of a capture probability from H-2 (P-C), leaving the H-2(+) in its ground state, and an excitation probability (P-E) of the residual target to a dissociative state. P-C is evaluated in the Continuum Distorted Wave-Eikonal Final State (CDW-EFS) model and P-E is calculated in the first Born approximation (FBA). The differential cross-sections are studied as a function of the molecular orientation and the interference patterns obtained are compared with the available experimental data.
