The emission of energetic light ions from heavy-ion induced reactions was studied by measuring coincidences of protons and alpha particles with (1) Z = 1 to 7 particles, (2) discrete ..gamma.. rays, and (3) ..gamma..-ray multiplicities from bombardment of /sup 60/Ni with /sup 12/C ions. Incident beam energies were 136 and 194 MeV. Discrete ..gamma.. rays were used to identify the residual target-like fragments. Most of the particle-particle coincident angular correlations are strongly peaked in the forward direction; the full width of half maximum of the proton distributions are typically 50/sup 0/, those of the alpha particles are 30/sup 0/. The N-Z distributions of the residual nuclei peak around /sup 60/Ni. The ..gamma..-ray multiplicities are insensitive to the energy of the gating energetic light ion and are about 9 for 136-MeV /sup 12/C projectiles and 10 for 194 MeV. The results indicate the contribution of more than one mechanism in producing the high-energy light ions. In part the energetic light ions are emitted in association with a projectilelike fragment. A major component of the energetic light ions can be explained as emission from the projectilelike fragment during the collision process followed by fusion of the remainder of the fragment with the target.
