Inclusive production cross sections of charged pions on carbon, copper and bismuth by neutrons in the energy range of 300-580 MeV have been measured from 54° to 164°. The invariant cross sections can be expressed by E dσ d3p=A exp(-Bp2) for the high-energy part of the pion spectra. The slope parameter exhibits a systematic variation with neutron energy and emission angle for the three targets. The dependence of the pion production on the target mass number varies strongly with pion energy and emission angle. The production cross sections are compared with the model of quasi-two-body scaling, the moving-source model and with intranuclear cascade calculations.
