"Table 2" of "eta-meson production in proton-proton collisions at excess energies of 40 and 72 MeV"

Differential cross section for pp -> pp eta at proton beam energies of 1360 and 1445 MeV (excess energies of of 40 and 72 MeV). The angle theta** is that between the pp relative momentum and that of the eta in the diproton rest frame. The error shown in the table is the combined statistical and systematic uncertainty, excluding the overall normalization error.
