An emulsion study has been made of pi /sup -/--nucleon interactions at a pion energy of 4.5 Bev. The percentage of elastic scattering at this energy seems slightly smaller than at energies slightly above 1.0 Bev. One can deduce from this that the range of interaction between pi /sup -/ and proton is greater than 1.0 t 10/sup -13/ cm. The inelastic interactions resulting in two prongs have been considered in some detail. The angular distributions are suggestive of a direct knock out of a pion by the incoming pion. Ihe momentum distributions obtained recentiy froin diffusion chamber work at Berkeley also seem to support such a model. The four- and six-prong events are more complicatcd. The data from all inelastic interactions indicate the nucleons seem to go strongly in the backward direction in the c.m. system. Thus none of the interactions scem consistent with the statistical model of pion production. (auth)
