MEASUREMENT OF THE EXCLUSIVE LIGHT HADRON DECAYS OF THE ψ″ IN e+e- EXPERIMENTS

The measurement of the exclusive light hadron decays of the ψ″ in e+e- experiments with significant interference between the ψ″ and continuum amplitudes is discussed. The radiative correction and the Monte Carlo simulation are studied. It is possible to verify the destructive interference for the detectors with energy–momentum resolution of (1~2)%.
