Abstract

We present results of experimental measurements and theoretical calculations for the spin asymmetry, A(Θ_B). of the triple differential cross section. Spin-polarized lithium atoms were ionized by spin-polarized electrons of 54.4 eV incident energy. The geometry was coplanar with one detector at a fixed angle (Θ_A = 35° or 45°). Three data sets were obtained for ratios of shared energy E_A/E_B = 8.8, 2.4, and 1. For the most asymmetric set the convergent close-coupling method gives best agreement, whereas for the symmetric set the distorted-wave Born approximation seems to be in better agreement.
