Abstract：
The experimental (n, 2n) cross sections around 14MeV have been collected, analyzed, and evaluated Data were taken from 124 nuclei for A=19—209 up to the end of 1984. Relation between σ_n, 2_n and (N—Z)/A has been studied. No neutron shell effect is found. The cross sections for some nuclei have been calculated by using a statistical theory. The good agreement with the experimental σ_n, 2_n at 14MeV has been obtained in terms of a single set of fitting parameters.
