Abstract
We investigate the effect of different relativistic spin couplings of const ituent quarks on nucleon electroweak properties. Within each quark spin cou pling scheme the correlations between static electroweak observables are fo und to be independent of the particular shape of the momentum part of the n ucleon light-front wave function. The neutron charge form factor is very se nsitive to different choices of spin coupling schemes once the magnetic mom ent is fitted to the experimental value. However, it is found rather insens itive to the details of the momentum part of the three-quark wave function model. (C) 2001 Elsevier Science B.V. All rights reserved.
