Spin-resolved superelastic electron scattering from sodium has been measured at total energies of 10 and 40 eV, for scattering angles between 10° and 140°. The angular momentum transfer, Lperp}, and the spin-resolved components L(Tperp} and L(S)perp} have

Measurements of the asymmetry in the scattering of unpolarised electrons from optically pumped spin-polarised sodium atoms have been carries out at incident electron energies of 20, 54.4, and 70 eV and for a range of scattering angles between 20° and 140°

Superelastic scattering of spin-polarized electrons from laser-excited sodium atoms has been measured at incident energies of 2.0, 17.9, and 52.3 eV over the angular range 10°-120°. Circularly polarized excitation of the sodium atoms was used to produce
Calculations of the exchange asymmetry in elastic scattering of electrons by sodium atoms are reported at incident electron energies of 10 and 54.4 eV. The close-coupling calculations are performed with the four lowest target states of the sodium atom. At

Measurements of superelastic scattering of 2eV electrons from oriented Na(3P) atoms have been carried out over the angular range 10 to 120°. Results are presented in terms of L perp}, the angular momentum transferred perpendicular to the scattering plane

We report the first measurements of elastic scattering of spin-polarized electrons from spin-polarized Na atoms as a function of scattering angle. The incident energy is 54.4 eV, and the angular range is 20° - 135°. Data are presented as an exchange
A general framework using density matrices is developed for the analysis of atomic excitation by spin-polarized electrons. This framework is applied to the specific case of the 3S 1/2rarr} 3P 3/2 transition in Na, as studied by the time-reversed
