Fully energy-damped yields from the ${}_{}{}^{32}{}_{}{}^{}\mathrm{Mg}$ reaction have been measured at center-of-mass energies of $E_{\mathrm{c}.\mathrm{m}.\mathrm{}=51.6\mathrm{}}$ and 60.5 MeV with the use of an experimental arrangement where both of the resulting heavy fragments could be detected in coincidence. Energy, velocity, and angular distributions of the reaction fragments have been determined. The cross sections prior to secondary light-particle emission have been deduced for the breakup of the compound system into different mass channels. These data are discussed in terms of two possible reaction mechanisms: fusion followed by fission and deep-inelastic orbiting.
