    Abstract

    Capture, elastic scattering and total cross section measurements were performed on 242Pu below 1300 eV. The neutron widths Γn were obtained for 71 resonances and the total radiative widths Γγ for 25 resonances. The s-wave strength function S0 = (0.89 -0.09+0.10)×10-4 and the average radiative width \ ̄gGγ = [21.9±0.4 (stat.)±1.0 (syst.)]. The resonance parameters were used to calculate the fission widths Γf from the fission cross section results of Auchampaugh et al. From these fission widths, the height of the second fission barrier is deduced: EB = 5.18 MeV.
