Using the CLEO II detector, we have measured the differential cross sections for exclusive two-photon production of light pseudoscalar mesons π0, η, and η. From our measurements we have obtained the form factors associated with the electromagnetic transitions γ*γ→meson. We have measured these form factors in the momentum transfer ranges from 1.5 to 9, 20, and 30 GeV2 for π0, η, and η, respectively, and have made comparisons to various theoretical predictions.
