Abstract
The Q2 dependence of the structure functions F2p and F2d recently meas ured by the NMC is compared with the predictions of perturbative QCD a t next-to-leading order. Good agreement is observed, leading to accura te 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 cou pling constant is measured from the low x data; the result agrees with previous determinations.
