title: Production of 3H at large momentum in alpha-12C collisions at 2A GeV.
abstract: Calculations of the longitudinal and transverse momentum distributions for 3H production at large momentum in alpha-12C collisions near 2 A GeV are compared to experiment.  Triton exchange and final-state interactions are shown to represent large corrections to the impulse approximation for proton knockout.  A method for calculating interference effects for inelastic fragmentation is discussed.  Good agreement with experiment is found using a phenomenological overlap function for 3H-p successful in describing 3H production in pion-induced reactions.  Comparisons to momentum distributions obtained through (p, 2p) and (e, ep) reactions on 4He are made.
