    "abstract": "In this note we generalized the Dirac non-linear electrodynamics, by\nintroducing two potentials (namely, the vector potential A and the\npseudo-vector potential gamma^5 B of the electromagnetic theory with charges\nand magnetic monopoles) and by imposing the pseudoscalar part of the product\nomega.omega* to be zero, with omega = A + gamma^5 B. We show that the field\nequations of such a theory possess a soliton-like solution which can represent\na priori a \"charged particle\", since it is endowed with a Coulomb field plus\nthe field of a magnetic dipole. The rest energy of the soliton is finite, and\nthe angular momentum stored in its electromagnetic field can be identified\n--for suitable choices of the parameters-- with the spin of the charged\nparticle. Thus this approach seems to yield a classical model for the charged\n(spinning) particle, which does not meet the problems met by earlier attempts\nin the same direction.",
