Investigating many-electron exchange effects in electron-heavy-atom scattering

Bellm, Susan; Lower, Julian; Stegen, Z; Madison, Don Harvey; Saha, H P


In a recent publication we presented measurements and distorted-wave Born approximation (DWBA) calculations for spin asymmetries resulting from the scattering of 148 eV spin-polarized electrons from ground-state xenon atoms. While achieving reasonably good agreement between theory and experiment by accounting for many-body exchange effects through a local exchange potential, sizable discrepancies remained in some cases. It was proposed that a more sophisticated treatment of exchange might be...[Show more]
