We precisely measured the ($$gamma$$, n) cross section for $$^{77}$$Se by developing a spectroscopic method utilizing Laser Compton-Scattering $$gamma$$-rays. Moreover, the $$^{79}$$Se(n, $$gamma$$) $$^{80}$$Se cross section was deduced using the statistical model calculation code CCONE with $$gamma$$-ray strength functions adjusted to reproduce the ($$gamma$$, n) cross sections for $$^{77}$$Se and the even Se isotopes $$^{76}$$Se, $$^{78}$$Se and $$^{80}$$Se. The reliability of the $$^{79}$$Se(n, $$gamma$$) $$^{80}$$Se cross section calculated by CCONE with the adjusted $$gamma$$-ray strength function was evaluated by comparing available experimental (n, $$gamma$$) cross sections for stable $$^{76, 77}$$Se isotopes and those calculated by CCONE with the adjusted $$gamma$$-ray strength function. The result provides fundamental data for the study of nuclear transmutation for the long-lived fission product of $$^{79}$$Se.
