Abstract

We have measured single-particle inclusive spectra of $π^{+}$ and $π^{-}$ mesons produced at 2.5° (lab) in the collision of 1.05-4.2-GeV protons, 1.05- and 2.10-GeV/nucleon deuterons and $α$ particles, and 2.10-GeV/nucleon ${}^{12}C$ nuclei with various targets at an angle of 2.5° (lab). The negative-pion spectra show scaling behavior. The results are compared to a simple model in which individual nucleons in the projectile interact with the target to produce pions.
