摘要：

Measurements were made at SLAG of the cross section for scattering 29 GeV electrons from carbon at a laboratory angle of 4.5 degrees, corresponding to 0.03 < x < 0.1 and 1.3 < Q(2) < 2.7 GeV2. Values of R = sigma(L)/sigma(T), were extracted in this kinematic range by comparing these data to cross sections measured at a higher beam energy by the NMC collaboration. The results are in reasonable agreement with pQCD calculations and with extrapolations of the R1990 parameterization of previous data. A new fit is made including these data and other recent results.
