Abstract
The Dalitz-decay contribution of neutral mesons to the di-electron invariant-mass spectrum at 1 AGeV is deduced from a systematics of meson production cross sections measured with the photon spectrometer TAPS. A comparison with recently published di-electron mass spectra of the DLS collaboration shows that eta Dalitz decay does not exhaust the e(+)e(-) yield in the mass range of 0.2-0.5 GeV/c(2).
