Activation technique was applied for the measurement of ground-state and isomeric-state cross-sections in the \(^{{74}}\)Se(n,2n)\(^{{73}}\)Se reaction within the 13–15 MeV neutron energy range to resolve inconsistencies in the existing database. \(\gamma \) rays with energy of 253.7 keV from the decay of the \(^{{73\text {m}}}\)Se isomeric-state and energy of 361.2 keV from the \(^{{73\text {g}}}\)Se ground state were recorded using a high-resolution high-purity germanium (HPGe) detector. A monoenergetic neutron beam was produced via the T(d,n)\(^{{4}}\)He. The cross-sections and isomeric ratios were also calculated using the TALYS-1.95 nuclear model code with different six-level density options at neutron energies varying from the reaction threshold to 20 MeV. Results are discussed and also compared with some corresponding values found in the literature.
