摘要: The emission of alpha projectile fragments has been studied in 16O-emulsion interactions at 3.7 A GeV.The angular distributions of relativistic alphas cannot be explained by a clean-aut participant-spectator model.Therefore it is assumed that alphas originate from two distinct sources differing in their temperatures.
