AbstractResonance scattering of a Dirac particle (electron) in a screened Coulomb potential (of Lorentz vector type) is investigated. The so-called direct and spin-flip differential cross sections for Dirac particles are analyzed by a partial- wave analysis, as well as the spin-polarization parameters, here denoted S, T and U. This model study of angular as well as energy behaviors shows that differential cross sections, at forward and backward angles, together with the polarization parameter T seem to be best indicators of energy and orbital angular momentum of sharp, isolated, resonances.
