NEGATIVE PION PRODUCTION IN RELATIVISTIC HEAVY ION COLLISIONS

Negative-pion production in relativistic heavy-ion collisions has been studied in a triggered streamer-chamber experiment with projectile nuclei /sup 12/C and /sup 40/Ar in the energy range 0.4-2.1 GeV/nucleon incident on targets LiH, NaF, BaI/sub 2/, and Pb/sub 3/O/sub 4/. Negative-pion yields, multiplicity distributions, and angular and momentum distributions are reported.
