NEGATIVE PION INTERACTIONS AT 1.3 Bev/C
A total of 340 meters of track of negative pions of momentum 1.3 Bev/C have been followed in emulsion, and pion interactions have been recorded. Special emphasis is placed on inelastic scattering on free protons (single meson production). The resulting angular and momentum distributions of the emitted particles are investigated and compared with previous experiments at similar energies. An attempt is made to explain these results on the basis of an isobar decaying into a nucleon and the slower pion. In the case of reaction pi /sup -/ + p red and pi /sup -/ + pi /sup o/ + p, it appears that there exists an anisotropy in the isobar frame of reference, in which the slower pion is emitted predominantly backward, with respect to the isobar direction. The results are compared with the pi - pi coupling model. Angular and energy distributions of mesons emitted in nuclear interactions are investigated and compared with other results and Monte Carlo calculations. The meson multiplicity and energy degradation in these collisions are also discussed. Strange particles found during the investigation are analyzed. (auth)
