Systematics of excitation function for (n, charged-particle) reactions

On the basis of an evaporation model in which preequilibrium emission is considered under some approximations, analytical expressions including two adjustable parameters for excitation function of (n, charged-particle) reactions have been derived. Fitting these expressions to the available measured data, these parameters have been extracted and the systematic behavior of the parameters has been studied. Charged-particle production data of neutron-induced reactions are of great importance from the viewpoint of fusion reactor technology, particularly for the calculations of nuclear transmutation rate, nuclear heating, and radiation damage due to gas formation
