Cross sections for evaporation residue products have been measured from /sup 86/Kr-bombardments of /sup 65/Cu, /sup 90/Zr, and /sup 109/Ag at energies ranging from 366 to 716 MeV. In the /sup 65/Cu and /sup 90/Zr cases, experimental sigma/sub E/R values are in agreement with predictions of statistical model deexcitation calculations in which angular-momentum-dependent fission competition has been included. The measured sigma/sub ER/ is considerably lower than the calculated value for /sup 109/Ag + /sup 86/Kr, but predictions are extremely sensitive to level density parameters in that case. Correlated mass-charge distributions of evaporation residue products have been measured from the reaction /sup 65/Cu + /sup 86/Kr at 316 and 716 MeV. At the higher energy, measured and calculated distributions are in excellent agreement with each other, and calculations are insensitive to assumptions made concerning the effect of particle emission on the angular momentum of evaporating system. At the lower energy, measured distributions are broader than calculated ones, and the theory is sensitive to specific assumptions concerning angular-momentum removal.
