Abstract: Events of the type e/sup +/e/sup -/ ..-->.. e/sup +/e/sup -/eta' (958) have been observed with the Mark II detector at SPEAR by detecting the decay mode eta' ..-->.. rho/sup 0/..gamma... From the observed cross section and known branching fractions of the eta' is GAMMA/sub gammagamma/ = 5.9 +- 1.6 +- 1.2 keV and the total width is GAMMA = 300 +- 90 +- 60 keV (statistical and systematic errors).
