| Abstract: | The fission cross section ratio of 243Am to 235U has been measured in the energy range of 1.1～6.8 MeV with monoenergetic neutrons. An ionization fission chamber was used to detect fission events. The quantitative analyses of the fission samples were made with a low geometry counter and a 2 π counter. Uncertainties of the measured data were analyzed considering correlations between error elements. The present result is very close to that of Fursov et al. and lower by about 20% than the values reported by Behrens & Browne. |
