Total and elastic scattering neutron cross sections of 239Pu

Abstract

Elastic neutron scattering cross sections of ²³⁹Pu are measured at ⪅50 keV intervals from 0·3−1·5 MeV with incident neutron resolutions of ≈20 keV. Total neutron cross sections are measured from 0·65 to 1·5 MeV at intervals of ⪅5 keV and with resolutions of ≈2·5 keV. The experimental results are compared with the predictions of optical- and statistical-models, with other measured values and with representative evaluated data.
