The available experimental data on isomeric ratios measured in (n,2n) reactions are re-evaluated using a method based on the Huizenga-Vandenbosch assumptions. So far only the experimental values of isomeric (n,2n) cross section ratios reported for nuclei with N<50 at 14 MeV have been re-analysed. The dependence of the extracted spin cut-off factors on the parameters used is discussed, and the latter are compared with the values predicted by the Fermi gas model; their ratios are found to be about 0.5.
