Abstract

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, L perpendicular to, and the spin-resolved components Lperpendicular to T and Lperpendicular to have been determined. The ratio, r, of triplet to singlet differential cross sections has also been found. The data are compared to theoretical calculations based on close-coupling and distorted-wave models. The spin-averaged Lperpendicular to and triplet Lperpendicular to T show good agreement with close-coupling theory while the singlet Lperpendicular to approximately= and the ratio r are poorly predicted. © 1991..
