We report the observation of intense constant kinetic energy emission structures, in the photoemission spectra of the divalent rare earth elements, Eu and Yb, in the solid state, when excited by photon energies larger than the 5p core ionization thresholds; and we propose a possible explanation of this phenomenon.

Abstract
We report the observation of intense constant kinetic energy emission structures, in the photoemission spectra of the divalent rare earth elements, Eu and Yb, in the solid state, when excited by photon energies larger than the 5p core ionization thresholds; and we propose a possible explanation of this phenomenon.
