Abstract
We report new results on a precision measurement of the ratio R = sigm a(L)/sigma(T) from hydrogen, deuterium, and beryllium targets for deep inelastic electron scattering in the range 0.1 less than or equal to x less than or equal to 0.7 and 0.5 less than or equal to Q(2) less th an or equal to 7(GeV/c)(2). We find no measurable difference between R (p) and R(d). Our results are consistent with, and more precise than, previous SLAG data. At high x, R is somewhat larger than order alpha(s )(2) pQCD predictions, even when target mass effects are included.
