Description
The reaction e+e- -> e+e-eta' (958) has been observed by detecting the final state π+π-γ. The two photon width of the eta' has been measured to be GAMMA(eta' -> γγ) = 5.1 +- 0.4 +- 0.7 keV. A search for the iota (1440) has been made in the rho0γ final state. An upper limit has been obtained for the product GAMMA(iota(1440) -> γγ), B(iota -> rho0γ) < 1.5 keV (95% C.L.). (orig.)
