The decay channels of ${}_{}{}^{238}{}_{}{}^{}\mathrm{U}*$ excited to energies between 10 and 1800 MeV are sampled by a microcanonical Monte Carlo calculation; i.e., the total energy, momentum, baryon number, and charge are strictly conserved quantities. From samples of about 2 × ${10}^6$ complete events, various averages are calculated, such as the number $N_c$ of charged fragments, the number of prompt and of evaporated neutrons, the temperrature, and the multiplicity of heavy fragments. The distributions of the multiplicity $N_c$ and of the temperature $T$ are calculated as well.
