We have measured the potassium {ital K}{sub {beta}} and chlorine {ital K}{sub {beta}} resonant Raman x-ray scattering from KCl. Strong {ital K}-shell absorption peaks are directly reflected in the resonant Raman spectra. The emission spectra are qualitatively evaluated in terms of the associated absorption spectra, based on a simple single-electron model of the scattering process. This model affords direct interpretation of the energy, line shape, and intensity variations of the emission spectra. In the resonant Raman regime, energy offsets between the data and the model predictions are attributed to binding energy differences between intermediate and final state excitons; thus these offsets indicate that the associated peaks in the absorption spectra are excitonic in nature. {copyright} {ital 1996 The American Physical Society.}
