Summary
A new formula for the (n, 2n) reaction cross-sections estimation at an energy of 14.5MeV has been obtained by employing the pre-equilibrium and evaporation models. The formula gives a more precise description of experimental data and represents the isotopic dependence of the cross-sections better than the systematics proposed earlier by other authors. Unlike other systematics, the formula obtained takes account of the difference in the cross-section values for nuclei of different parity.
