摘要：

A careful new measurement of the U-238(n, gamma) cross section from 10 eV to 100 keV has been made using the DANCE detector at LANSCE. DANCE is a 4 pi calorimetric scintillator array consisting of 160 BaF2 crystals. Measurements were made on a 48 mg/cm(2) depleted uranium target. The cross sections are in general in good agreement with previous measurements. The gamma-ray emission spectra, as a function of gamma multiplicity, were also measured and compared to model calculations.
