"Table 1" of "eta-meson production in proton-proton collisions at excess energies of 40 and 72 MeV"

The Svedberg Lab Uppsala. Measurement of the cross sections for the production of ETA mesons in Proton-Proton collisions at proton beam energies of 1360 MeV and 1445 MeV, corresponding to excess energies of 40 Mev and 72 MeV respectively. The ETA was detected through its 2 photon decay in a near-4PI electromagnetc calorimeter with the Protons measured with a combination of straw chambers and plastic scintillator planes in the forward hemisphere. Note the comments on the labelling of the axes on the figures in the paper. Numerical values supplied by H Petren.

乌普萨拉斯韦德贝格实验室（Svedberg Lab Uppsala）测量了质子束能量分别为1360 MeV和1445 MeV的质子-质子碰撞中η介子（ETA meson）的产生截面，对应过量能量分别为40 MeV和72 MeV。实验中，η介子通过其双光子衰变道，由近4π电磁量能器（electromagnetic calorimeter）探测；质子的方位则通过前向半球内的straw管室（straw chamber）与塑料闪烁体平面的组合系统完成测量。请注意论文中图表坐标轴标注的相关说明。本数据集的数值由H·佩特雷伦（H Petren）提供。
