We study the electronic structure of Mott-Hubbard systems SrVO3 and CaVO3 with photoemission spectroscopy (PES) using hard Xrays (HX) (hv similar to 8 keV) and soft X-rays (SX) (hv similar to 900 eV). In HX-PES results, the V 2p core levels of SrVO3 and CaVO3 show clear additional intensity, which are not observed in SX-PES. These features originate from bulk screening by coherent states at Fermi level as observed in other 3d transition metal oxides. From the comparison between SrVO3 and CaVO3 in HX-PES, the intensity in SrVO3 is nearly similar to CaVO3. The results suggest screening from coherent states is more efficient in HX-PES compared to SX-PES. (c) 2006 Elsevier B.V. All rights reserved.
