Mass and velocity distributions have been measured for the evaporation residue and fusion-fission products from the ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$${+}^{40}$Ca reaction at 214 MeV. Comparisons of Monte Carlo statistical evaporation simulations to the observed angle and mass dependences of the evaporation-residue velocity distributions were used to set limits on the maximum complete-fusion cross section and to extract information about the magnitude and character of incomplete-fusion processes. The extracted value of the complete fusion evaporation-residue cross section is discussed in the framework of previous results and existing models.
