These measurements are made as a function of momentum transfer $-t$, with significantly higher statistical precision than our earlier $\\eta$ measurements, and are the first measurements of $\\eta^{\\prime}$ in this energy range. We compare the results to theoretical predictions based on $t$--channel quasi-particle exchange. We also compare the ratio of $\\Sigma_{\\eta}$ to $\\Sigma_{\\eta^{\\prime}}$ to these models, as this ratio is predicted to be sensitive to the amount of $s\\bar{s}$ exchange in the production. We find that photoproduction of both $\\eta$ and $\\eta^{\\prime}$ is dominated by natural parity exchange with little dependence on $-t$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.110166.v1/t1","@type":"Dataset","description":"Values and errors for the photon beam asymmetry $\\Sigma_{\\eta}$ for the reaction $\\gamma p \\rightarrow \\eta p$ with $\\eta\\rightarrow\\gamma\\gamma$.
