A generalization of the Boltzmann master equation theory in order to e
valuate the angular distributions of the ejectiles emitted during the
nucleon-nucleon interaction cascade which brings about the thermalizat
ion of the composite nucleus formed in the fusion of two heavy ions is
discussed. The spectra of light ejectiles, up to alpha-particles, pro
duced in many projectile-target combinations, and at many different re
lative energies of the two ions are very reasonably reproduced. (C) 19
