摘要：

We report experimental results on the cross section for the reaction e+e- → hadrons as a function of the total c.m. energy in the range W = 1.42-3.09 GeV. The results, combined with those already existing below the charm threshold, clearly indicate a structure for R(W) = α(e+e- → hadrons)/α(e+e- → μ+μ-) in that energy region. © 1979.
