Abstrakt: The fraction of the total available energy carried by photons and the fraction carried by neutral particles of all types ine+e- multihadron final states have been measured at three centre-of-mass energies between 12 and 35 GeV. These fractions are approximately 27% and 37% with no strong dependence on centre-of-mass energy and the event topology. The neutrino energy fraction is estimated to be less than 10% at the 95% confidence level.
