摘要：

Electronic excitations in the correlated metal BaTi0.02V0.98S3 have been studied using resonant inelastic soft x-ray scattering at the V L edge. The intensities of the intra-atomic d-d* excitations and the elastic x-ray scattering feature are found to be temperature dependent, with the intensity increasing with decreasing temperature until saturation is reached near 100 K. The behavior of the spectral features is interpreted as evidence of a shift in the 3d electrons from more band-like states at higher temperature to more localized states at low temperature.
