Spin asymmetries in low-energy electron scattering from cesium atoms

Baum G, Raith W, Roth B, et al. Spin asymmetries in low-energy electron scattering from cesium atoms. Phys.Rev.Lett. 1999;82(6):1128-1131.Experimental benchmark results for the differential cross section and several spin asymmetries are presented for elastic electron scattering from Cs atoms at an energy of 3 eV. Comparison with predictions from several nonrelativistic, semirelativistic, and fully relativistic theoretical models emphasizes the need for the development of a numerical approach that accounts both fur relativistic effects and for coupling between a large number of discrete and continuum target states.
