Two-photon interactions have been studied with the SLAC-LBL Mark II magnetic detector at SPEAR. The cross section for eta' production by the reaction e/sup +/e/sup -/..-->..e/sup +/e/sup -/eta' has been measured at beam energies from 2.0 to 3.7 GeV. The radiative width GAMMA/sub gammagamma/(eta') has been determined to be 5.8 +- 1.1 keV ( +- 20% systematic uncertainty). Upper limits on the radiative widths of the f(1270), A/sub 2/(1310), and f'(1515) tensor mesons have been determined. A search has been made for production of the E(1420) by ..gamma gamma.. collisions, but no signal is observed.
