The transport of monoenergetic neutrons in spherical geometry with forward
scattering and vacuum boundary conditions is considered. The scaled transpo
rt equation is solved using the F-N method by considering the pseudo-slab p
roblem. Numerical results for the fundamental and higher order eigenvalues
are presented for several significant figures. Some selected results are co
mpared with those obtained using various methods in the literature. Finally
, a few remarks about the behavior of the critically eigenvalue of the neut
ron transport equation with forward scattering is given.
