The electromagnetic form factors are computed using eigenstates of linear momentum for the nucleon. The latter is described in the framework of the chiral color-dielectric model, projecting the hedgehog ansatz on eigenstates of angular momentum and isospin. Form factors are well reproduced, with the
The ratio of the proton elastic electromagnetic form factors, GE/GM, has been measured for Q2 values from 0.5 to 3.5 (GeV/c) 2. The ratio was found to decrease with increasing Q2, in contrast with an approximately constant value indicated by earlier experiments.
The detection of the e+e ---\* ~n reaction at the Adone collider by the Fenice Collaboration has allowed to measure for the first time the neutron electromagnetic form factors in the time-like region, from threshold to 2.44 GeV center of mass energy. After a brief description of apparatus and data r
