Target residues from the interaction of copper with 15, 25, 35, and 45 MeV/nucleon {sup 12}C ions have been studied by off-line {gamma}-ray spectroscopy. Cross sections, average ranges, and forward-to-backward ratios were measured for some 35 products. The data were used to obtain the isobaric yield distribution and the mass yield distribution. The isobaric yield distribution remains essentially unchanged in the energy regime studied while the mass yield distribution changes substantially. The results have been compared with both evaporation and preequilibrium model calculations on the assumption that the initial interaction involves incomplete fusion. Neither model can satisfactorily account for all the results. The data were also used to obtain the mean longitudinal momentum transfer (LMT) and the mean excitation energy. The mean LMT attains a maximum value of 1.7 {+-} 0.1 GeV/c at 25 MeV/nucleon. The fractional LMT decreases continuously from approximately 0.8 at the lowest energy to 0.4 at the highest one. The mean excitation energy initially increases with energy but appears to level off at the higher energies.
