In attempts to extract the high density nuclear equation of state (EOS) from intermediate energy heavy ion collisions much attention has focused on simulating these using the Boltzmann-Uehling-Uhlenbeck [1, 2] (BUU) transport equation, which describes the time evolution of the one-body nucleon phase space distribution function f(r, p, t):
$$\frac{{\partial f}}{{\partial t}} + v.\frac{{\partial f}}{{\partial r}} - \frac{{\partial U}}{{\partial r}}.\frac{{\partial f}}{{\partial p}} = - \frac{1}{{{{\left( {2\pi } \right)}^6}}}\int {{d^3}{p_2}{d^3}} {p_2},d\Omega \frac{{d{\sigma _{NN}}}}{{D\Omega }}g \left\{ {\left[ {f{f_2}\left( {1 - {f_{1\prime }}} \right)\left( {1 - {f_{2\prime }}} \right) - {f_{1\prime }}{f_{2\prime }}\left( {1 - f} \right)\left( {1 - {f_2}} \right)} \right]{{\left( {2\pi } \right)}^3}{\delta ^{\left( 3 \right)}}\left( {p + {p_2} - {p_{1\prime }} - {p_{2\prime }}} \right)} \right\}. $$
