The experimental data for $(n, 2n)$ reaction cross-sections around 14 MeV neutron energy have been collected from the literature and analysed for the isotopes having $1 \leq Z \leq 82$. The empirical relations for the reaction cross-sections have been obtained, which show fairly good fits with the experimental values. The shell effects have been established at magic nucleon numbers for $(n, 2n)$ reaction cross-sections around 14 MeV neutron energy. The odd–even effects have also been observed as the cross-sections for odd-mass nuclei are higher than their neighbouring even–even nuclei.
