Abstract

Measurements of the reactions

e^{+} + e^{-} \to e^{+} + e^{-}

μ^{+} + μ^{-}

, and

τ^{+} + τ^{-}

at PETRA energies (

s^{\frac{1}{2}} = 13, 17, 27.4, 30 and 31.6

GeV) are reported. The results show that these reactions agree well with the predictions of quantum electrodynamics thus determining that all the known charged leptons are pointlike particles to a distance < ×

10^{- 16}

cm.
