Phys. Rev. C 60, 025206 (1999) [6 pages]Nucleon form factors in a chiral constituent-quark modelReceived 19 January 1999; published 23 July 1999 The electromagnetic form factors of the nucleon have been calculated in a chiral constituent-quark model. The nucleon wave functions are obtained by solving a Schrödinger-type equation for a semirelativistic Hamiltonian with an effective interaction derived from the exchange of mesons belonging to the pseudoscalar octet and singlet and a linear confinement potential. The charge-density current operator has been constructed consistently with the model Hamiltonian in order to preserve gauge invariance and to satisfy the continuity equation. © 1999 The American Physical Society URL:
