| contents | We propose to search for (ultra)-light scalar dark matter (DM) using synchrotron radiation based Mössbauer spectroscopy technique. Such DM induces temporal variation in various fundamental constants, which in turn causes time modulation of the nuclear transition energies. When a Mössbauer source and absorber is separated by a large baseline, the DM induced shift between their energy levels can be tested by the modulation of the photon absorption spectrum. The narrow Mössbauer transitions allow the setup to efficiently probe DM in the high frequency range. We show that the reach of a Mössbauer experiment with the existing synchrotron beams is at par with the bounds from various equivalence principle violation searches. An improvement of the synchrotron setup would enable us to probe the hitherto uncharted territory of the DM parameter space upto MHz frequency. The proposed method would extend the DM search beyond the EP limit by several orders of magnitude, and would provide the best bound on DM interaction strength with various standard model fields in the high ($>$kHz) frequency region. |
