A recent high-resolution measurement of the neutron fission cross section of {sup 239}Pu has allowed the extension from 1 to 2 keV of a previously reported resonance analysis of the neutron cross sections, and an improvement of the previous analysis in the 0.3- to 1-keV range. The purpose of this paper is to describe the results of a consistent multilevel resonance analysis, from 300 eV to 2 keV, of the new fission cross-section measurement of Weston and Todd and of the transmission measurements of Harvey et al. The resonance analysis computer code SAMMY was utilized to perform the analysis using the Reich-Moore multilevel R-matrix formalism.
