Second Order Born Effects in the Perpendicular Plane Ionization of Xe (5p) Atoms

Abstract

We report triple differential cross section (TDCS) results for the perpendicular plane ionization of xenon atoms at incident electron energies 5eV, 10eV, 20eV, 30eV and 40eV above ionization potential. The TDCS calculation have been preformed within the modified distorted wave Born approximation formalism including the second order Born (SBA) amplitude. We compare the (e, 2e) TDCS result of our calculation with the very recent measurements of Nixon and Murray (Phys. Rev. A 85, 022716 (2012)) and relativistic DWBA-G results of Illarionov and Stauffer (J. Phys. B: At. Mol. Opt. Phys. 45, 225202 (2012)) and discuss the process contributing to structure seen in the differential cross section.
