Abstract

In this paper, we present the result of soft X-ray photoemission spectroscopy and its comparison with the density functional calculation. Although local density approximation seems to be a good starting point for describing the electronic structure of FeSe, the simulated spectrum poorly reproduced the structure around EB=2eV. This result suggests the necessity of theoretical treatment beyond local density approximation.
