Neutron multiple scattering due to elastic collisions inside DU target and corresponding energy losses were simulated. Also angular distribution was obtained for the neutrons outside of the target. The angle was measured w.r.t. the initial beam direction. The neutron beam was pencil-like w/o divergence monoenergetic (1 MeV) and hitting the center of the target normally to the surface of DU target. [math]10^6[/math] neutrons were initially incident upon the target. The target was composed of DU and had a cylindrical shape with diameter 7 cm and thickness 4 mm.
