Title

Spin Dependence of (e, 2e) Collisions on Lithium at 54.4 eV

Abstract

We present results of experimental measurements and theoretical calculations for the spin asymmetry, A(ΘB). 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 (ΘA = 35° or 45°). Three data sets were obtained for ratios of shared energy EA/EB = 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.
