Energy spectra and multiplicities of neutrons from the reaction system 838 MeV 32S projectiles on 197Au have been measured in coincidence with binary fragmentations. Neutron detection was performed simultaneously in a 4re scintillator sphere and by time-of-flight. The linear momentum transfer (LMT) and the excitation energy E~N are deduced with the folding angle technique. Neutron multiplicities are compared for consistency and discussed as a measure of LMT and E*N. The saturation of M4~(E*N) beyond E*N ~ 400 MeV seen for several systems of high fissility (x > 0.8) is attributed to the spreading of the folding angle distribution and the increasing competition of charged particle evaporation.
