MEASUREMENT OF THE RADIATIVE WIDTH OF THE ETA'(958) IN 2-PHOTON INTERACTIONS
The reaction e+e-→e+e-η′(9 58) has been observed by detecting the final state π+π-γ. The two-photon width of the η′ has been measured to be Γ(η′→γγ) = 5.1±0.4±0.7 keV. A search for the ι(1440) has been made in the ρ{variant}0γ final state. An upper limit has been obtained for the product Γ(ι(1440) →...
