摘要：

Using the CLEO II detector, we have measured the differential cross sections for exclusive two-photon production of light pseudoscalar mesons pi(0), eta, and eta'. From our measurements we have obtained the form factors associated with the electromagnetic transitions gamma* gamma-->meson. We have measured these form factors in the momentum transfer ranges from 1.5 to 9, 20, and 30 GeV2 for pi(0), eta, and eta', respectively, and have made comparisons to various theoretical predictions.
