Abstract Study of α particles, protons and neutrons emission in reactions induced by16O on Sn targets. The threshold for direct a emission is found to be v/c−0.04 (v velocity of the projectile at the top of the Coulomb barrier) whereas direct protons and neutrons, if any, would be emitted for beam energies higher than 7.8MeV/n. (v/c〉0.092). Atv/c 0.092, 90% of the direct a cross section is shown to be incomplete fusion. On116Sn target, besides the main exit channels α4n and αp4n, we observed 2α4n and α2p4n channels where the direct α is followed by evaporation particles. This implies a lower initial angular momentum than for the main channels.
