A Monte Carlo program, evolved for the photon problem, is being applied by using photon source data from neutron fluxes calculated by a combination of age and diffusion theory. A modification of the Carlson S/sub n/ method and a direct analytical method are described which were considered for solving the integro-differential transport equation in the neutron spectra determinations. An analytical solution was developed for the case of isotropic scattering in the laboratory system. (B.O.G.)
