The cross section for the process e+e− → multihadrons has been measured at the highest PETRA energies. We measure R (the total cross section in units of the point-like e+e- → μ+μ- cross section) to be 2.9 ± 0.7, 4.0 ± 0.5, 4.6 ± 0.4 and 4.

The radiative decays of J ψ into f/γ, f′γ, ππγ and KKγ have been measured using the double arm spectrometer DASP at DORIS. We find B(J/φ→fγ)=(J/φ→fγ)/(J/φ→all)=(0.9±0.3)×10−3 to (1.5±0.4)×10−3 depending on the multi- pole
