Theory and application of the double Pn method in slab geometry for isotropic neutron sources and scattering

Abstract

A simple matrix formalism is developed to facilitate the application of the double PN method of spherical harmonics to multiple slab configurations, representative of some of the basic neutron transport problems in the theory of nuclear reactors. Special attention is given to the double P2 and P3 approximations, and the results of numerical computations are compared with known accurate results.
