N2  - The angular distribution of H+ fragment ions produced in 5&#8211;25 keV H+&#8211;H2 collisions was investigated in coincidence with Lyman-&#945; photons. The observed photons arise from electron capture to the projectile H(2p) state and/or from the fragmentation of the H2 molecule via 2s&#963;g, 2p&#963;u or 2p&#928; u states of the excited H+2* ion. An analysis of the measured angular distributions has been performed to distinguish the separate degenerate channels available to an emitted Lyman-&#945; photon. The results show similarities to the data of Lindsay et al. (1987) who measured the non-coincident angular distribution of H+ fragment ions within the same energy range.
