NUCLEON FORM-FACTORS IN THE RELATIVISTIC QUARK-MODEL - BEHAVIOR AT SMALL AND INTERMEDIATE MOMENTUM-TRANSFERS AND QCD ASYMPTOTIC-BEHAVIOR

It is shown that in the region of relatively small momentum transfer (Q2 less-than-or-equal-to 3 GeV2) the simplest quark diagram without gluon exchanges gives a good description of the nucleon form factors. The perturbative contributions to the magnetic form factors at currently accessible Q2 are negligibly small and opposite in sign to experiment, i.e., the model predicts a change of sign of the nucleon magnetic form factors at high Q2.
