A modifiedN/D method is applied for the cases of3He charge and magnetic form factors. Anomalous cut positions are computed using possible exchanges at the photon-3He electromagnetic vertex. and one of them is found atta=0.0618 GeV2. TheD-function is used to parametrize the two-pion cut while theN-function is taken to represent the effect of an anomalous or the three-pion cut. Excellent fits to the available experimental data on charge and magnetic form factors are obtained and several useful information on the form factors computed.
