FIG. 1.
Two-color stimulated RIXS scheme in the CO driven by a pair of temporally overlapping SASE pulses. (a) The pump field of frequency ωp is resonant to the intermediate core-excited state ; the probe field of frequency ωd stimulates inelastic Raman scattering channel from the core-excited to a valence-excited state . (b) Generalized electronic-vibrational level scheme of stimulated RIXS in molecules.
