Calculation of the passage of fast neutrons through graphite

  • L. M. Shirkin


Using the Monte-Carlo method, the author calculates the results of passing neutrons from a plane unidirectional source, with E0=3.3 or E0=8.0 MeV, through graphite. The angle of incidence is taken as 0°. The graphite layer thicknesses considered are from 0.9 to 6 times the free-path length. The author calculates the dose, energy and numerical albedos of graphite and also the angular and energetic distributions of the reflected neutrons and the angular distribution of the energy of scattered neutrons. He plots the mean cosine of the angle of scattering vs. the albedo, and also vs. the value of the energy angulardistribution constant. The data obtained may be found useful in the design of shadow and labyrinth shielding.
