The Q2 dependence of the structure functions F2p and F2d recently measured by the NMC is compared with the predictions of perturbative QCD at next-to-leading order. Good agreement is observed, leading to accurate determinations of the quark and gluon distributions in the range 0.008 less-than-or-equal-to x less-than-or-equal-to 0.05. The strong coupling constant is measured from the low x data; the result agrees with previous determinations.

Abstract
The Q2 dependence of the structure functions F2p and F2d recently measured by the NMC is compared with the predictions of perturbative QCD at next-to-leading order. Good agreement is observed, leading to accurate determinations of the quark and gluon distributions in the range 0.008 less-than-or-equal-to x less-than-or-equal-to 0.05. The strong coupling constant is measured from the low x data; the result agrees with previous determinations.
