The predictions of a variety of current theoretical models of high-energy nuclear collisions are compared with recent experimental data for central collisions of /sup 20/Ne on /sup 238/U at E/sub lab/ = 393 MeV/n. The experimental observation of broad sideward maxima in the angular distributions of low- and medium-energy protons is reproduced by a nuclear fluid dynamical calculation with final freezeout of the protons. In contrast, the current intranuclear-cascade and simplified collision models predict forward-peaked angular distributions.
