摘要
We discuss the applicability of pQCD to the elastic scattering of electrons on protons and deuterons. We analyze the Q(2)-dependence of the reduced deuteron form factor, taking into account the recent data on the electric proton form factor and we find that the value of the QCD-scale parameter Lambda differs essentially from the value Lambda = 0.1 GeV, previously found using the dipole parametrization of the electromagnetic nucleon form factors G(E) and G(M). Moreover, the predicted scaling behavior of the reduced deuteron form factor, cannot be recovered in the Dirac and Pauli representations for the nucleon electromagnetic form factors.
