摘要

计算了无限稀释238U在第一分辨能级(6·7 eV)和1 MeV之间的共振吸收积分。利用核模型理论和可分辨共振区确定了平均吸收截面的能量无关参数Γn0/D和Γγ/Γn0。0中子很小，但很重要。277±10%谷仓的总数值与试验值吻合较好。

The resonance absorption integral of 238U

The resonance absorption integral of infinitely diluted ²³⁸U is calculated between the first resolved level (6·7 eV) and I MeV. The energy-independent parameters Γ_n⁰/D and Γ_γ/Γ_n⁰ of the average absorption cross-section are determined from the region of resolved resonances and the nuclear model theories, The effect of l > 0 neutrons is shown to be small but significant. The total value of 277 ± 10 per cent barns is in good agreement with experiment.
