Title: Spin-resolved Superelastic Scattering from Sodium at 10 and 40 eV
Published: December 28, 1991
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{perp}, and the spin-resolved components L(T{perp} and L(S){perp} 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 L{perp} and triplet L(T){perp} show good agreement with close-coupling theory while the singlet L(S){perp} and the ratio r are poorly predicted.
