ON THE CALCULATION OF THE FUNDAMENTAL MODE OF THE ONE-VELOCITY NEUTRON TRANSPORT OPERATOR

Abstract

We report here some results on the asymptotic behavior of a neutron pulse injected into a slab using monoenergetic transport theory including the effects of the anisotropic scattering cross section in the laboratory system. The calculations were performed in the P1 and P3 approximations. These results are compared with the exact numerical calculations and with the recent pulsed neutron experiments in fast nonmultiplying nonmoderating assemblies where the decay of an essentially monoenergetic burst of neutrons is studied.
