The momentum distribution of fragments produced in the [sup 12]C + [sup 12]C reaction at 28.7 MeV/nucleon is analyzed with an antisymmetrized version of molecular dynamics. Calculations are made for several cases of stochastic collisions and the projectile-fragmentation peak in the momentum distribution is reproduced by the incorporation of the many-body nature into the stochastic collision process. Furthermore, the value of the cross section is found to be reflected in the low-momentum part of fragments such as [alpha] particles and [sup 9]Be.
