DIRAC BOUND STATES IN A ONE-DIMENSIONAL SCALAR SCREENED COULOMB POTENTIAL

In this paper we illustrate the existence of genuine bound states for a Dirac particle interacting with a scalar screened Coulomb potential in a 1 + 1 dimension. In contrast to the bare Coulomb potential, the screened Coulomb potential can bind both spin-zero and spin-1/2 particles in the scalar prescription.
