An investigation of 281 interactions of 2-Bev/c negative pions with emulsion nuclei is reported. The fraction of stars with charged secondary pions is 75 plus or minus 3 per cent, and the mean number per star of emitted charged pions is 1.21 plus or minus 0.08. Only 2 K mesons are observed, which result confirms that the production cross section of strange particles is low. The results are compared with the predictions from a cascade calculation that starts from the known elementary pion-nucleon and nucleon-nucleon cross sections. The agreement between the calculated data and the experimental results is good as far as the multiplicity, energy spectrum, and angular distribution of emitted pions and the energy spectrum of knock-on protons are concerned.
