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 -} {yields} e{sup +}e{sup -}{eta}' has been measured at beam energies from 2.0 GeV to 3.7 GeV. The radiative width {Lambda}{sub {gamma}{gamma}}({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.
