Abstract
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.
