Pion production was studied at E/sub lab//A = 35 MeV in the reactions /sup 14/N+Al, Ni, W..--> pi../sup 0/+X. Neutral pions were measured by detecting their two decay ..gamma.. rays in coincidence in an array of ten Pb-glass Cherenkov-detector telescopes. The measured cross sections are much larger than predicted within the framework of independent nucleon-nucleon collisions and indicate that, at this energy, pion production is the result of cooperative action among many nucleons.
