    Abstract

    The baryon form factor gV of the vector current is investigated. We demonstrate that the d-type contribution to gV is proportional to the matrix element of a decuplet operator between baryon states. Hence, if a dynamical mechanism exists which suppresses such matrix elements, the neutron charge form factor will be small even for nonzero q2. This provides an explanation for the observed vanishing of the neutron charge radius.
