Abstract : The cross section of the process $\rm e^+e^-\rightarrow Ze^+e^-$ is measured with ~0.7\,fb$^{-1}$ of data collected with the L3 detector at LEP. Decays of the Z boson into quarks and muons are considered at centre-of-mass energies ranging from $183$ GeV up to $209$ GeV. The measurements are found to agree with Standard Model predictions, achieving a precision of about 10\% for the hadronic channel.
