A semi-analytic method of solving the neutron transport problem for a homogeneous scattering and absorbing sphere with an isotropic central point source is described. The method consists essentially of a modified Neumann series approach in which the Neumann series is constructed for the difference between the finite problem and the closely related problem in infinite geometry.
