INELASTIC $pi$$sup -$-NUCLEON INTERACTIONS AT 6.8 Gev IN THE BUBBLE CHAMBER
Pictures taken from a 24-1 propane bubble chamber exposed to negative pions of (6.8 plus or minus 0.6) Bev/c momentum are scanned for inelastic pion- nucleon interactions. A total of 171 inelastic pi /sup -/ nucleon events is found. The distribution of momenta, angles, and transverse momenta are given. The results are compared with those of inelastic pionnucleon interactions in nuclear emulsions. It is found that about 20% of the interactions identified in the propane bubble chamber are events which, in nuclear emulsion, would not show up as pion-nucleon collisions. From an investigation of the accidental and systematic errors in the momentum determination it is concluded that distortions in the: bubble chamber and on the photographic film cannot be neglected if high momenta are measured.
