Signatures in spectroscopy arise from the interference between the probing light and the field scattered by the sample. Imprinting relative phases to the two channels enables one to engineer the spectrum, e.g., by turning absorption lines into Fano profiles [1,2].
In this contribution, we report on recent experiments, in which we implemented the phase control by mechanically displacing a target of Mössbauer nuclei after its excitation with resonant x-rays.
