Abstract Within the quasi free-reaction model apart from the conventional component of direct fragmentation we include also particles coming from the interaction of the socalled participant, part of the projectile, with the target. The model takes into account the momentum distribution of clusters in the projectile, the off-energy-shell cross section for a virtual two-body reaction and the phasespace factor. The last two factors have usually been neglected in studies of heavy ion fragmentation. The model has been applied to the description of inclusive energy spectra of particles produced in the12C+12C collision, measured at the energy of 85 MeV/A by the CERN-Copenhagen-Grenoble-Lund collaboration. With two parameters adjusted to the experimental data, the model describes the energy spectra at forward angles and predicts the slope of the experimental angular distributions.
