氢中产生强子的 γ 射线总截面 σ T 已在 265-4215 MeV 的能量范围内测量。采用了具有狭窄能量箱的标签系统。观察到共振区域的结构，然后能量稳定下降，并对结果进行了分析。评估了 γ-质子散射的前向振幅，并研究了其在 Argand 图中作为能量函数的行为。详细说明了测量结果与Regge-pole 理论和矢量优势模型的关系。
The total cross section of γ rays in hydrogen resulting in hadron production, σ T, has been measured over the energy range 265-4215 MeV. A tagging system with narrow energy bins was employed. Structure in the resonance region followed by a steady fall with energy has been observed and the results are analyzed. The forward amplitude of γ-proton scattering is evaluated, and its behavior in the Argand diagram studied as a function of energy. The relationships of the measurements to Regge-pole theory and the vector-dominance model are detailed.
