Resonant soft-x-ray emission spectroscopy was measured on La{sub x}Sr{sub 1{minus}x}TiO{sub 3} (x=0,&hthinsp;0.05,&hthinsp;0.10) in the Ti&hthinsp;2p energy region. At the Raman scattering of the e{sub g} resonance, the d-d transition whose Raman shift has an energy value of about 2.3 eV corresponds to the crystal-field splitting. On the other hand, at the t{sub 2g} resonance, the d-d transition whose Raman shift is about 2.2 eV is thought to be the transition reflecting half intra-atomic Coulomb energy. {copyright} {ital 1999} {ital The American Physical Society}
