On the inverse problem of transport theory with azimuthal dependence

Abstract
The infinite medium inverse problem with an azimuthally dependent plane source leads to integral moments of the intensity over all space and angle. A new relationship has been derived between the moments and the coefficients of the expansion of powers of ν in terms of the gmk(ν) polynomials which arise in transport problems without azimuthal symmetry. This relationship has been used to obtain an improved method for determining the moments.
