The (γ, n) cross sections of Se isotopes (76Se,78Se) were measured to supply fundamental data for estimating the inverse reaction cross section, i.e., the 79Se(n, γ)80Se cross section. The enriched samples and a reference 197Au sample were irradiated with laser-Compton scattering (LCS) γ-rays. The excitation function of each (γ, n) cross section was determined for the energy range from each near neutron separation energy to the threshold energy of (γ, 2n) reaction. The energy point corresponding to each cross section was deduced using the accurately determined energy distribution of LCS γ-rays. Systematic (γ, n) cross sections for Se isotopes including 80Se were compared with those calculated by using a statistical model calculation code TALYS.
