"Table 3" 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.

乌普萨拉斯韦德贝里实验室（Svedberg Lab Uppsala）开展了一项实验测量：针对质子束能量为1360 MeV与1445 MeV（对应过剩能量分别为40 MeV与72 MeV）的质子-质子碰撞过程，测定η介子（ETA meson）的产生截面。η介子通过双光子衰变道在近4π立体角电磁量能器（electromagnetic calorimeter）中被探测，质子则通过前向半球内的漂移室（straw chamber）与塑料闪烁体平面的组合装置完成测量。请注意论文中各图表的坐标轴标注相关说明。本数据集的数值由H·佩特伦（H Petren）提供。
