Abstract

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