The 80Se(γ, n)79Se cross section was measured with laser-Compton scattering (LCS) γ-rays to supply fundamental data for the estimation of the inverse reaction cross sections, i.e., the 79Se(n, γ)80Se cross section. An enriched 80Se sample and a reference 197Au sample were irradiated with LCS γ-rays whose maximum energy was varied from 10.5 to 16.0 MeV. The energy distributions of LCS γ-rays were precisely determined using a high-resolution high-energy photon spectrometer (HHS). Emitted neutrons were detected by a high-efficiency 4π-3He detector. The excitation function of the 80Se(γ, n) cross section was determined for the energy range of 10.2–14.6 MeV. The energy point corresponding to each cross section was deduced using the accurately determined energy distribution of LCS γ-rays.
