TN approximation to neutron transport equation and application to critical slab problem

The critical slab problem has been studied in one-speed neutron transport equation with isotropic scattering by using the TN method. TN moment criticality solutions are obtained for the uniform finite slab using Mark and Marshak type vacuum boundary conditions. Results obtained by TN method, using the two type boundary conditions mentioned above, were presented in the Tables and also the Tables included the results obtained by PN method for the comparisons.
