Abstract：
On the basis of Planck formula of black body radiation and experimental data, an empirical systematic formula with two djustable parameters is presented. For incident proton energies from threshold to 1 50MeV and target masses in 44<A<239 and 44<A<242 region, this formula can describe (p, n) and (p, 2n) reaction cross sections nicely.
