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.
