Taking into account compound, pre-equilibrium and direct reaction mechanisms, we suggest certain method for theoretical explanation of systematic regularity in the fast neutron induced (n,p) reaction cross sections. The statistical model, Griffin exciton model and PWBA are used. For systematical analysis of (n,p) reaction cross sections, simple and convenient formulae are deduced. It is shown that theoretical (n,p) cross sections are satisfactorily in agreement with experimental values for the 6, 8, 10, 13, 14.5, and 16 MeV neutrons.
