Abstract
A new semi-empirical formula for the calculation of the (n,p) cross section at 14.5 MeV neutron energy is proposed. Derived from the evaporation statistical model, the formula includes five parameters and shows a strong dependence of the (n,p) cross section on terms of the parameters (N-Z+1)/A, (2Z-1)/A and √A . Fitting this formula to the existing cross section data on 159 nuclei (between A=40 and 209), the adjustable parameters were determined and the systematics of the (n,p) reaction were studied. The predictions of this formula are compared with those of the existing formulae and with the experimental data. The formula with five parameters is found to give a better fit to the data than the previous comparable formulae.
