In this study, the ²³⁶U(n,γ) reaction cross section has been measured for the incident neutron energy range from 10 eV to 800 keV by using the Detector for Advanced Neutron Capture Experiments (DANCE) γ-ray calorimeter at the Los Alamos Neutron Science Center. The cross section was determined with the ratio method, which is a technique that uses the ²³⁵U(n,f) reaction as a reference. The results of the experiment are reported in the resolved and unresolved resonance energy regions. Individual neutron resonance parameters were obtained below 1 keV incident energy by using the R-matrix code sammy. The cross section in the unresolved resonance region is determined with improved experimental uncertainty. Lastly, it agrees with both ENDF/B-VII.1 and JEFF-3.2 nuclear data libraries. In conclusion, the results above 10 keV agree better with the JEFF-3.2 library.
