Description
The current experimental and theoretical studies on resonant coherent excitation (RCE) of relativistic highly charged ions in crystals and, especially those on its two-color variant are shown as a model for future polarization and angular correlation XFEL measurements in keV energy region. The variety of combinations of the frequency ranges between the partners in typical RCE processes - from almost equal to each other keV photons in the case of two-step excitation of ionic autoionizing states to the opposite strongly asymmetric case of soft, of several eV, pumping radiation combined with probing keV X-Rays in the Autler-Townes RCE investigations - shows certain perspectives for theoretical, experimental and engineering work concerning XFELs.
