The Boltzmann-Uehling-Uhlenbeck and relaxation time methods are compared numerically for collisions between two {sup 16}O nuclei. Phase-space trajectories and double differential cross sections for nucleon emission are compared. Results are practically identical although the relaxation time method exhibits a slightly higher degree of stopping power.
