Wohl, M L

A Monte Carlo program was written for the IBM 7090 computer. The code considers protons in the primary galactic energy range (0.1 to 10 Bev) impinging at angles of 0, 30, 45, and 60 deg , as well as isotropically, on an infinite slab of aluminum 55 cm thick. The average proton nuclear collision density in each of six laminar regions of the slab is computed. In addition, the energy distribution of evaporation neutrons from the resulting excited nuclei is computed, and the statistical model is assumed to be valid. The proton collision density may be used as the spatial source density distribution for calculations of the transport of the secondary neutrons. (auth)
