We measured the Mn {ital L}{sub {alpha},{beta}} x-ray fluorescence spectra of MnO excited by selected photon energies near the {ital L}{sub 2,3} absorption edges. The resulting resonant inelastic x-ray scattering spectra probe low-lying electronic excited states, due to {ital dd} and charge-transfer excitations. Using a two-step model and a purely atomic approximation, we reproduce both energies and varying intensities of {ital dd} excitations relative to the electronic recombination peak. Our results show that strongly varying line shapes in resonant x-ray emission need not be due to channel interference effects. {copyright} {ital 1996 The American Physical Society.}
