【 摘 要 】

A new measurement of the ²³⁷U(n, f) cross section from thermal to ??? 100 keV is discussed, using one of the flightpaths at the LANSCE Lujan Center. Previous energy-resolved resonance-region measurements have been conducted using weapon test time-of-flight[1] and the LANSCE Lead Slowing Down Spectrometer[2], the former of which is limited in its energy range, and the latter in its energy resolution and range. We present here a proposal, based on simulations of the Lujan Center neutron flux and a hypothetical experiment, that is expected to adequately address both of these issues.
