Description
We observe a resonancelike structure in the total cross section for hadron production by e+e- colliding beams at a mass of 4414 +- 7 MeV having a total width GAMMA = 33 +- 10 MeV. From the area under this resonance, we deduce the partial width to electron pairs to be GAMMA/sub ee/ = 440 +- 140 eV. Further structure of comparable width is present near 4.1 GeV
