Abstract: (APS)

The nucleon's strange form factors GES(Q2) and GMS(Q2), and the neutron's electromagnetic form factors GEn(Q2) and GMn(Q2), are obtained from the light-cone quark model including the quark anomalous moments due to the meson-loop corrections. The anomalous magnetic and strange moments of the constituent quark make significant contributions: Without them, GMS(0) vanishes, rS2 becomes positive, and the neutron charge radius is too small.
