  A model describing nuclear collisions at intermediate energies is presented
and the results are compared with recently measured double differential cross
sections in C-C reactions at 95 MeV/nucleon. Results show the key role played
by geometrical effects and the memory of the entrance channel, in particular
the momentum distributions of the two incoming nuclei. Special attention is
paid to the description of processes occurring at mid-rapidity. To this end, a
random particle production mechanism by means of a coalescence process in
velocity space is considered in the overlap region of the two interacting
nuclei.
