| Tóm tắt: | The aim of this study was to determine correction parameters to improve the accuracy in measurements of the neutron capture cross-section on filtered neutron beams at Dalat nuclear research reactor. Computer codes to calculate these factors for effect of resonance capture at low energy background, multi scattering, and shelf shielding have been developed based on the methods of Monte - Carlo, Neutron transmission and Unfolding. The calculated and experimental results of neutron background spectra for 53.9 keV and 148.3 keV filtered neutron beams and the correction factors for nuclei of 197Au, 139La, 191Ir, 193Ir, and 152Sm are reported. |
