For accuracy improvement of fast-neutron capture reaction data of long-lived MA in a fast neutron energy region, the evaluation of gamma-ray strength function, which is important in the calculation of capture cross sections by the statistical model, was made with a comparison between calculated and measured pulse-height spectra. The results of capture cross sections calculated with the obtained gamma-ray strength function will be presented.
