The Greuling-Goertzel approximation is applied to the calculation of neutron slowing down in heavy water in the B1 and P1 approximations. Numerical calculations of the flux and nonescape probability assuming constant cross sections indicate the “inconsistent” G-G B1 approximation to be the most favorable. Existing machine codes can readily be modified to this method.
