Abstract
The electromagnetic form factors of the soliton are derived with the o ne-quark loop approximation in the semi-bosonized SU(3) Nambu-Jona-Las inio model in the collective formulation. Compared to the SU(2), there are anomalous currents which are finite and are not regularized due t o the imaginary part of the Euclidean effective action in addition to the usual currents which are regularized. We evaluate the magnetic mom ent for the octet baryons and find that the model without the boson lo op and the vector mesons predicts low values generally. Also, relevant problems are discussed.
