Angular Dependance of Auger electrons from N$_{2}$

POSTER

Abstract

One of the primary goals for x-ray free electron lasers (xFELs) is the study of x-ray interactions in the molecular-frame. Impulsive molecular alignment can be used to bring the molecular frame into the laboratory frame without perturbing the electronic states. We present molecular frame Auger electron spectra corresponding to quasi-bound final states of N$_{2}^{2+}$. We compare experimental and calculated angular distributions of Auger electrons and find good qualitative agreement. These and potential future measurements could lift ambiguity in previous $KLL$-Auger energy assignments.
