Two-source emission of relativistic alpha particles in 16O-Em interactions at 3.7 A GeV
3.7 A GeV 16O与乳胶作用相对论性α粒子的双源发射

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.
