Abstract
A measurement of absolute integrated luminosity is presented using the CLEO II detector operating at the CESR e+e- storage ring. Independent analyses of three different final states (e+e-, γγ, and μ+μ-) at √s {reversed tilde equals} 10 GeV normalize to the expected theoretical cross sections and correct for detection efficiencies. The resulting luminosities are measured with systematic errors of ±1.8%, ±1.6%, and ±2.2%, respectively, and are consistent with one another. The combined luminosity has a systematic error of ±1.0%.
