Abstract
We discuss the applicability of pQCD to the elastic scattering of
electrons on protons and deuterons. We analyze the
Q2-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
differs essentially from the value
GeV, previously found using the dipole parametrization
of the electromagnetic nucleon form factors
GE and
GM.
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.
