Abstract

Cross sections for elementary processes relevant in the modeling of negative ion sources are reviewed, with particular attention to the dependence on the vibrational excitation of the target molecule. Electron impact induced excitation and dissociation processes in H2 molecule and its isotopic variants are considered. Ro-vibrationally resolved cross sections for dissociation and de-excitation occurring in atom-molecule collision processes are presented. Finally the theoretical determination of hydrogen recombination probability on graphite surface is also considered. © 2005 American Institute of Physics.
