Recent experiments by Baum, Raith, and co-workers to measure the spin-induced asymmetries in electron scattering from cesium have stimulated theoretical work to interpret these measurements. We present Dirac R -matrix calculations of the interference asymmetry function, and of the spin-orbit and spin-exchange asymmetries, for comparison with experimental data at 7 and 13.5eV and with nonrelativistic predictions of the spin-exchange asymmetry from the convergent close coupling method. We find that a simple relativistic target model provides a basis for the understanding and analysis of ongoing experiments. {copyright} {ital 1997} {ital The American Physical Society}
