摘要：

The results of a systematic study of 0°pion production by heavy ions from 125 to 400 MeV/nucleon are presented. The dependence of the cross section on the mass number of the target, the energy of the beam, and the pion charge and energy are discussed. A striking feature of the data is an unexpectedly large π-π+ ratio for pions of valocity close to the projectile velocity. © 1979 The American Physical Society.
