Phys. Rev. A 70, 012707 (2004) [13 pages]Angle-differential cross sections and spin-asymmetry parameters for spin-polarized electron-impact excitation of spin-polarized cesium atomsSee Also: Publisher's Note Received 19 March 2004; published 13 July 2004; corrected 28 July 2004 Relative angle-differential cross sections and spin-asymmetry parameters are presented for spin-polarized electron-impact excitation of spin-polarized cesium atoms for incident projectile energies ranging from 5 eV to 25 eV. The experimental data, obtained in the angular range of 40° to 140°, are compared with predictions from a nonrelativistic convergent close-coupling treatment for the differential cross section and the (spin) exchange asymmetry and from a semirelativistic R matrix with pseudostates approach. The latter also yields nonzero values for two other spin asymmetries that require the presence of explicitly relativistic effects such as the spin-orbit interaction. The overall agreement between the experimental data and the theoretical predictions is satisfactory. © 2004 The American Physical Society URL:
