Abstract
We calculate nucleon form factors in the framework of a chiral chromod ielectric model. The model state describing the nucleon is an angular momentum and isospin eigenstate with J = T = 1/2 obtained by means of Peierls-Yoccoz projection from the hedgehog. We present results for th e electromagnetic form factors and also for the axial form factors of the nucleon. There is a fairly good agreement with the data for small momentum transfers. For high momentum transfers (i.e. q2 > 0.1 GeV2) t he agreement becomes poorer. As a general rule the calculated form fac tors fall too rapidly.
