Abstract:

An investigation of 281 interactions of 2 GeVc negative pions with emulsion nuclei is reported. The fraction of stars with charged secondary pions is 753 per cent, and the mean number per star of emitted charged pions is 1.21 0.08. Only 2 K-mesons have been observed, which confirms other results that the production cross section of strange particles is low. Our results have been compared with the predictions from a cascade calculation by Metropolis et al. which starts from the known elementary pion-nucleon and nucleon-nucleon cross sections. The agreement between the calculated data and our experimental results is good as far as the multiplicity, energy spectrum and angular distribution of emitted pions and also the energy spectrum of knockon protons are concerned.
