description A preliminary, high precision measurement of the luminosity of the LEP colliding beams for the LEP I data recorded between 1993 and 1995 with the OPAL experiment is presented, the measurement is based on the OPAL Silicon-Tungten luminosity monitor, which detects electrons from small-angle Bhabha scattering at angles between approximately 25 and 58 mrad. The overall experimental uncertainty on the measured luminosity is 3.3*10/sup -4/. Such uncertainty contributes negligibly to the uncertainty on the OPAL cross section measurements near the Z /sup 0/ resonance. (3 refs).
