DIFFERENTIAL FAST-NEUTRON ALBEDOS FOR CONCRETE. VI. RESULTS OF MONTE CARLO CALCULATIONS FOR AN INCIDENT ANGLE OF 85 DEG

The report is one of a series of six reports presenting experimental and calculated differential fast-neutron albedos for concrete. The experiment was conducted at the ORNL Tower Shielding Facility and consisted of measuring neutrons reflected at various angles from a concrete slab which had been placed in a highly collimated beam of neutrons from the TSR-II (four angles of incidence). The calculations were performed with the 05R Monte Carlo computer code and covered six different source energy bands for each angle of incidence of a 'gun barrel' source of monodirectional neutrons. Volume VI presents the machine output in detail for a different angle of incidence of 85 deg. See also AD-622 329, AD-644 103.
