Angle Resolved Photoemission Spectroscopy of Single Crystal Uranium (001)

ORAL

Abstract

Using Angle Resolved Photoemission Spectroscopy (ARPES) we measured the energy dispersion for binding energy (BE) $<$ 8 eV at 173 and 373 K on a high quality uranium single crystal (001) along the principle crystallographic directions $\Gamma $ to Y, $\Sigma $, and S. These measurements are compared with WIEN2K band structure calculations. We report significant correspondence between our band dispersion and theoretical calculations. Temperature and electron correlation effects will be discussed.
