Phys. Rev. A 67, 044702 (2003) [4 pages]Spin asymmetries in spatially resolved processes of ionization of heavy atoms by relativistic electronsReceived 7 September 2002; published 22 April 2003 The triple-differential cross section for ionization of a heavy atom is shown to depend on the spin of the incident electron even if this is polarized entirely parallel or antiparallel to its direction of propagation, the atom is unpolarized, and the spins of the ejected electrons are not resolved. Quantitative predictions for the spin asymmetry are presented in a relativistic distorted-wave Born approximation. Simple physical models are introduced to understand both these results and further symmetry properties involving the reversal of a spatial momentum component also. © 2003 The American Physical Society URL:
