An apparatus consisting of a superconducting solenoidal magnet, cylindrical drift chambers, and two arrays of lead--glass Cerenkov counters was used at the CERN ISR to study the production of e/sup +/e/sup -/ pairs of invariant mass larger than 6 GeV/c/sup 2/. Measurements of (d/sup 2/sigma/dmdy)/sub y=0/ for the e/sup +/e/sup -/ continuum and of B(dsigma/dy)/sub y=0/ for the UPSILON resonances will be presented for ..sqrt..s = 62.4 GeV. The mean p/sub T/ of the e/sup +/e/sup -/ pairs and the multiplicity and momentum spectrum of associated particles will be discussed. 6 references.
