The results of an R matrix analysis of the 239Pu neutron cross sections up to 1000-eV neutron energy are reported. The analysis was performed with the multilevel multichannel Reich-Moore code SAMMY. The method of analysis is described, and the selection of experimental data is discussed. Some tabular and graphical comparisons between calculated and measured cross sections and transmissions are presented. The statistical properties of the resonance parameters are examined. The resonance parameters are proposed for the new evaluated data files ENDF/B-VI and JEF2.
