Dyson orbitals from electron momentum spectroscopy

Abstract

Electron momentum spectroscopy has involved the verification of an ab initio model for the target-ion overlap, or Dyson orbital, in a calculation of a high-energy (e,2e) reaction by comparing the resulting cross section with experimental data. We describe an inverse method of extracting the overlap directly from experimental data by using a quantum-mechanically constrained statistical fitting procedure in conjunction with previously verified reaction models.
