Abstract : The angular distribution for elastic nucleonnucleon scattering at the high energy is sharply peaked in the forward direction. As a consequence, there is an angular interval in nucleon-nucleus scattering to which successive small-angle elastic nucleon-bound nucleon scatterings are more likely to contribute than a single nucleon-bound nucleon scattering through the angle of observation. Such plural collisions result in outgoing nucleons which have suffered a smaller energy loss than nucleons that are scattered from hydrogen at the same angle. T e Fermi motion of the bound-nucleons produces a broadening in the energy distribution of the scattered nucleons, but displaces the centre of the distribution only negligibly. The results of calculations with a simple model are in satisf ctory agreement with the observations on proton-carbon scattering. (Author)
