摘要：

New data for the reaction e+e-→Υ{hooked}(9.46) have been obtained using the DASP detector at the DORIS storage ring. The electronic width Γee is (1.5±0.4) keV. The branching ratio for the decay into muon pairs is (2.5 ± 2.1)%. Energy spectra for inclusive production of hadrons are given. © 1979.
