Collision spectroscopy of Ar8++H-2 at low velocities (upsilon < 1 a.u.)

Single and double electron transfer have been studied for the collision sys tem Ar8++H-2 at low velocities (V<1 a.u.). X-ray ultraviolet and Auger spec troscopies complemented by translational energy gain and time-of-flight spe ctroscopies reveal details on the transfer mechanisms: in contrast to the o ther two-electron target system (He target), a channel is opened where elec tron capture takes place with further dissociation of H-2(+) We consider th e target fragment dynamics and discuss possible molecule dissociation mecha nisms.
