Abstract
A new treatment of scattering, which conserves the total angular momentum and accounts for differences in {ital n}-{ital n}, {ital n}-{ital p}, and {ital p}-{ital p} cross sections, is proposed for use in the Vlasov-Nordheim (or Boltzmann-Uhling-Uhlenbeck) simulations of heavy-ion collisions. This treatment is used in the classical Vlasov-Boltzmann simulations of the collisions between two equal mass ({ital A}=50) nuclei at {ital E}{sub lab}{approx gt}400 MeV/nucleon. By comparison with the exact results for such collisions, it is shown to be significantly more accurate than the commonly used method in which the angular momentum is not exactly conserved.
