Measurement of the total hadronic cross section in e+e- annihilation below 10.56 GeV

Using the CLEO III detector, we measure absolute cross sections for e{sup +}e{sup -}{yields}hadrons at seven center-of-mass energies between 6.964 and 10.538 GeV. The values of R, the ratio of hadronic and muon pair production cross sections, are determined within 2% total root-mean-square uncertainty.
