Resonant Photoemission Spectra of the Valence and Ce 4d States of CeRu_2 : Effect of Coster-Kronig Decay on Energy Exchange between Two Continuum States

スポンサーリンク

概要

• 論文の詳細を見る

• The valence and Ce 4d photoemission spectra of CeRu_2 were measured in the 3d-4f resonance region without being complicated by strong Auger lines. Because of the strong Coster-Kronig decay channel the resonance due to 3d_<3/2>-4f excitation was found to be much weaker than that for 3d__<5/2>-4f excitation both for the valence and the 4d spectra. The spectral shape of the valence and the 4d electrons were changed in the two resonance regions, and especially the changes in the 4d spectra were drastic near the 3d_<3/2>-4f excitation region. A tentative interpretation of the drastic change is given in terms of an energy exchange between two continuum states following the Coster-Kronig decay.
