摘要：

We have measured differential cross sections of γ + p → p + η0 at several energies. The angular distributions show that S11 production is predominant in the energy range investigated and that the other resonant terms seen in π-production of η are absent or very low. Finally, experimental data are theoretically interpreted and the S11 parameters deduced. © 1969.
