【 摘 要 】

We measure the vibrational distribution of Hj ions issued from charge transfer in H++ H2collisions to probe the details of the electron transfer mechanism from low to high impact energies. The experiments are accompanied by theoretical calculations. This joint experimental-theoretical study allows us to elicit the adequacy and accuracy of widely used assumptions in the description of molecular collisions.
