Abstract

Small angle scattering of 280 GeV positive muons by deuterium, carbon and calcium has been measured at scattering angles down to 2 mrad. The nucleon structure function F₂ extracted from deuterium does not show a significant x dependence in the measured range of Q² and its Q² dependence is linear in logQ². For calcium, a depletion of F₂ is observed at low x by 30% as compared with the values at x = 0.1 where F₂(Ca) and F₂ (D) are not significantly different. This depletion is attributed to shadowing. The carbon structure function exhibits a similar, but less pronounced, x dependence. Such behaviour is observed to be independent of Q². The data are consistent with those obtained from other charged lepton experiments both at similar and higher values of x and Q² and considerably extend the range of the measurements down to the low values of x to be measured in forthcoming experiments at HERA.
