摘要：

The Υ{hooked}′ state has been observed as a narrow resonance at M(Υ{hooked}′) = 10.02 ± 0.02 GeV in e+e- annihilations, using a NaI and lead-glass detector in the DORIS storage ring at DESY. The ratio G{cyrillic}eeG{cyrillic}had/G{cyrillic}tot of electronic, hadronic, and total widths has been measured to be 0.32 ± 0.13 keV. The parameters of the G{cyrillic} particle have also been determined to be/M(G{cyrillic}). © 1978.
