They propagate as quantum particles with dispersion relation of a massive particle. We construct here explicitly such solutions for the massless Dirac equation, Weyl equation, and as a limiting case, the Pauli equation.en10.1016/0375-9601(94)90096-5info:eu-repo/semantics/closedAccessParticle-Like ConfigurationsElectromagnetic-FieldArticle1894277280N/AWOS:A1994NT006000032-s2.0-0001247260Q2
