【 摘 要 】

Fully differential cross sections for electron impact ionization of H2are determined experimentally using a reaction microscope. For dissociation of the final H2+ion in its electronic ground state the measurement of the proton momentum allows to conclude on the molecular alignment during the collision. The cross sections obtained are compared to published theoretical data.
