Abstract (data abstract)
CERN-LEP. Measurement of the differential cross sections in double-tagged two-photon collisions resulting from E+E- interactions at c.m. energies 189 to 209 GeV. The data are given as functions of the photon virtualities Q1 and Q2, thetwo-photon mass W and of the variable LN(W**2/Q1*Q2) for an average photon virt uality of 16 GeV**2. The data come from LEP-II and have a integrated luminosity of 617 PB-1.
