We have performed an alternative resonant x-ray emission (RXE) experiment involving a transition-metal ion in the gas phase. The complex spectral behavior is explained by an Anderson impurity model taking into account bound and continuum states and Coster-Kronig transitions. Low-energy excitations corresponding to the ligand field splitting are identified. We find that spectra are quite different from recent RXE from solid-state Ti4+ compounds. An unexpectedly strong resonance involving Coster-Kronig transitions is explained. Good agreement between theory and experiment is obtained without inclusion of a full intermediate state multiplet calculation.
