The Chebyshev polynomial approximation (U-N method) is used to solve the critical slab problem in one-speed neutron transport theory using Marshak boundary condition. The isotropic scattering kernel with the combination of forward and backward scattering is chosen for the neutrons in a uniform finite slab. Numerical results obtained by the U-N method are presented in the tables together with the results obtained by the well-known P-N method for comparison. It is shown that the method converges rapidly with its easily executable equations.
