Mr. Adams et al., EXTRACTION OF THE RATIO F-2(N) F-2(P) FROM MUON-DEUTERON AND MUON-PROTON SCATTERING AT SMALL-X AND Q(2)/, Physical review letters, 75(8), 1995, pp. 1466-1470
The ratio of the deuteron to proton structure functions is measured at
very small Bjorken x (down to 10(-6)) and for Q(2) > 0.001 GeV2 from
scattering of 470 GeV muons on liquid hydrogen and deuterium targets.
The ratio F-2(n)/F-2(p) extracted from these measurements is found to
be constant, at a value of 0.935 +/- 0.008 +/- 0.034, for x < 0.01. Th
is result suggests the presence of nuclear shadowing effects in the de
uteron. The dependence of the ratio on Q(2) is also examined; no signi
ficant variation is found.
