Abstract

We report new results on a precision measurement of the ratio R = σ L /σ T from deuterium, iron and gold targets, on the ratio σFe/σD and on the structure function F 2, for deep inelastic electron-nucleus scattering in the range 0.2 < x < 0.5 and 1 ≤ Q 2 ≤ 10(GeV/c)2. We find no difference between R Fe and R d. Our results show, for first time, a clear falloff of R with increasing Q 2 at SLAC energies. Our R and F 2 results are in good agreement with QCD predictions only when corrections for target mass effects are included.
