We consider the reaction ${}_{}{}^{36}{}_{}{}^{}\mathrm{Ar}$${+}^{197}$Au at incident ${}_{}{}^{36}{}_{}{}^{}\mathrm{Ar}$ energies of 35, 50, 80, and 110A MeV, comparing calculations of precompound decay using the Boltzmann master equation (BME) and quantum molecular dynamics (QMD) models. We then estimate quasiequilibrated nuclei and excitations using the BME, and use these values as input into statistical multifragmentation models. For the latter we compare sequential binary decay as an extension of the Weisskopf-Ewing evaporation model, and a simultaneous multifragmentation for an expanded low density gas. The exclusive multiplicities predicted by these models are compared with experimental results.
