Abstract

Abstract : The 77 Se (γ, n) cross section was measured for the energy range from 7.6 to 13.8 MeV by using quasi-monochromatic laser-Compton scattering γ-rays. The advanced method to deduce γ-ray strength functions from (γ, n) cross section was developed. By utilizing the method, the γ-ray strength functions of 77, 78, 80 Se were deduced so as to reproduce the 77, 78, 80 Se (γ, n) cross sections measured in this work and previous systematic measurements. The inverse (n, γ) cross sections for 76, 77, 79 Se isotopes were calculated using the statistical model calculation code CCONE with the deduced γ-ray strength functions. The uncertainty of the calculated 79 Se(n, γ) 80 Se cross section was evaluated by comparing the calculations and the experimental data on 76, 77 Se (n, γ) cross sections.
