Results obtained by two experiments at SPEAR on the two-photon production of lepton pairs and resonances are reported. Both experiments find agreement of lepton production with QED expectations, and observe an enhancement of the ..pi pi.. mass spectrum in the 1250 MeV/c/sup 2/ region. The Mark II finds this enhancement not consistent with the decay of the f(1270 MeV/c/sup 2/) alone. The ..gamma gamma.. partial width of the eta' has also been measured by the Mark II.
