[en] The weak-interaction contributions to the anomalous magnetic and electric dipole form factors of muon, electron and heavy leptons as well as their static values have been calculated in the framework of the Lee-Weinberg SU(3)xU(1) unified model of weak and electromagnetic interactions. It has been shown that the X₁, X₂ neutral gauge boson exchange diagrams, which may be responsible for the CP violation effects in the SU(3)xU(1) model, yield the leading contribution to weak-interaction correction to the electron and muon magnetic moments in comparison with contributions of the rest W, U, Y, Z boson exchange diagrams. The essential limitations on the SU(3)xU(1) model parameters have been obtained using the experimental data concerning the anomalous magnetic moment of muon and electric dipole moment of electron
