Abstract: (Elsevier)

Bose–Einstein correlations in W-pair production at LEP are investigated in a data sample of 629 pb −1 collected by the L3 detector at s =189 –209 GeV. Bose–Einstein correlations between pions within a W decay are observed and found to be in good agreement with those in light-quark Z decay. No evidence is found for Bose–Einstein correlations between hadrons coming from different W's in the same event.
