Abstract:
In order to provide information on the effectiveness of the conversion of negative hydrogen ions in collision with multiply charged ions into neutrals for plasma heating, the present situation is reviewed on the cross sections involving negative hydrogen ions in collisions with electrons, ions, atoms and molecules. It is pointed out that, though electron detachment from negative hydrogen ions is estimated to be effectively achievable under collisions with multiply charged ions, reliable data for such processes are still scanty in particular at the MeV/amu energy range and measurements of the cross sections are deserved to be performed urgently.
