Abstract

The first partial cross-section measurements are presented for the various channels of H₃⁺ and H₂ dissociation in collisions with helium atoms at 50 and 60 keV/amu. The experimental technique includes the use of a removable grid in front of a surface barrier detector to enable neutrals of mass 2 amu to be separated into H₂ and 2H channels.
