摘要：
The neutron capture cross-sections of U-238 at the neutron energies of 4.38 +/- 0.05 MeV, 3.02 +/- 0.49 MeV and 2.04 +/- 0.26 MeV have been measured using the activation method and off-line gamma-ray spectrometric technique. The effects of neutron flux fluctuation, multiple scattering, flux self-shielding and gamma-ray self-absorption were corrected. The excitation function of the U-238(n,gamma)U-239 reaction was also calculated using the TALYS-1.9 code. The experimental results were compared with the evaluated data, the theoretical data and the previous experimental data.
