In this paper, anisotropic transport-theory corrections to asymptotic diffusion theory are suggested and evaluated. These modifications are found to provide a natural and useful extension of diffusion-theory applications in one-dimensional, one-region problems. An effort is also made to determine whether the treatment of problems of more than one dimension in one-dimensional codes can be improved through the use of this extended formulation of diffusion theory.
