  Employing a four-body classical model, various mechanisms responsible for the
production of fast light particles in heavy ion collisions at low and
intermediate energies have been studied. It has been shown that at energies
lower than 50 A MeV, light particles of velocities of more than two times
higher than the projectile velocities are produced due to the acceleration of
the target light-particles by the mean field of the incident nucleus. It has
also been shown that precision experimental reaction research in normal and
inverse kinematics is likely to provide vital information about which mechanism
is dominant in the production of fast light particles.
