The target fragment production cross sections, angular distributions, and range distributions have been measured for the interaction of 12--16 MeV/nucleon {sup 32}S with {sup 165}Ho. The fragment isobaric yield distribution and the fragment moving frame angular distributions have been deduced from the data. Symmetry properties of the moving frame angular distributions have been used to establish a relative time scale for the reaction mechanism(s). No fission fragment moving frame angular distribution is symmetric about 90{degree}, suggesting that these products are produced, in part, by a fast, non- equilibrium process. The range distributions are used to deduce energy spectra, which suggest that the heavy residues are the result of complete or incomplete fusion and also of an inelastic process such as deep inelastic scattering.
