2014 (English)In: Physica Scripta, ISSN 0031-8949, E-ISSN 1402-4896, Vol. 89, no 8, 085401- p.Article in journal (Refereed) Published
Resonance 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 (DCSs) 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 DCSs, at forward and backward angles, together with the polarization parameter. seem to be best indicators of energy and orbital angular momentum of sharp, isolated, resonances.
