Reaction of np $Yields$ pp$pi$$sup -$ between 1.0 and 8.0 GeV/c
Results for 3564 events of the type np yields pp pi /sup -/ are presented. The events were obtained in a hydrogen bubble chamber exposed to a neutron beam. The incident momentum distribution of the events is approximately uniform in the ange 1.O - 7.5 GeV/c. The physical distributions are found to be in good agreement with the predictions of a one pion exchange model incorporating a recent phase shift analysis of pion-nucleon scattering and using the off-mass- shell corrections of Benecke-Durr and Durr-Pilkuhn. Certain discrepancies between our results and previous studies of the reaction in deuterium are found. In particular no evidence is found for anomalous N*(145O) production and discrepancies are found in certain momentum transfer distributions. (auth)
