Measurements were made at SLAC 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 GeV^2. 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.

The deep-inelastic electron-scattering cross sections per nucleon σA for D, He, Be, C, A1, Ca, Fe, Ag, and Au were measured in the kinematic range 0.09<~x<~0.9 and 2<~Q2<~15 (GeV/c)2 with use of electrons with energies ranging from 8 to 24.5 GeV. The ratio σAσD is consistent with unity in the range 0.1
