Energy and angular distributions of π's produced in relativistic heavy-ion collisions have been measured at 800 MeV/A incident energy. Cross sections for low-energy pions (Ecm ≈ 100-200 MeV) are forward and backward peaked in the nucleon-nucleon c.m. frame. Such anisotropy becomes weaker for higher energy pions. The shape of the energy spectra at θcm = 90° is approximately exponential. Their slopes are steeper than those observed for protons. The data are discussed in terms of several models.
