Abstract:

EHHE ENERGY-ANGLE DISTRIBUTIONS OF FAST NEUTRONS TRANSMITTED THROUGH SLAB SHIELDS ARE ANALYSED. Comparisons of calcula dd and measured angle distributions show that a six-energy group, double P sub 2 approximation is adequate for polyelyylene-slab calculations. Phenomenological arguments are presented which show that the transmitted energy-angle distribution can be described in terms of a simple asymptotic model. Suggestions for improving the asymptotic theory are included. Author
