We have measured cross sections for evaporation residues, fission, and direct and evaporative /sup 1/H and /sup 4/He in reactions of 222--340-MeV /sup 40/Ar with /sup 116/Sn, /sup 154/Sm, /sup 164/Dy, and /sup 197/Au. Fusion cross sections are also presented for 77--167-MeV /sup 12/C+/sup 182/W and 187-MeV /sup 40/Ar+/sup 116/Sn. The Z dependence of the evaporative H/He indicates a breakdown of phase-space models for fission-evaporation competition. The large cross sections observed for direct H/He emission force serious consideration of energy dissipation by H/He ejection during the initial impact.
