Summary:The electronic structure of the single crystal La0.7Sr0.3MnO5 in ferromagnetic metallic phase has been investigated by photoelectron spectroscopy. Valence band spectra were measured at 40 K for various photon energies, in the range of 45-70 eV. The Mn 3d partial density of states was derived from resonant photoemission near the Mn 3p-3d threshold. Besides the occupied 3d states, resonant photoemission data has provided information about the unoccupied 3d states. The value of the on-site Coulomb interaction strength (correlation energy) was estimated to be 6.7eV.
