Pion production from heavy-ion collisions is calculated in the independent-particle model, with nucleon--nucleon cross section data as input information. The assumption is made that only the first collision of a nucleon pair can create a pion, and also all collective effects are neglected. For the representative case of /sup 16/O bombardment of /sup 238/U at 250 MeV/nucleon, one out of seven inelastic collisions should produce a pion. One-third of these pions should be able to escape to the outside. The pion spectrum peaks at 20 MeV with an average energy of 50 MeV, viewed in the nucleon--nucleon cener-of-mass frame.
