Precision Spectroscopy Division

Overview of the Precision Spectroscopy Division

The Precision Spectroscopy Division supports public beamtime work using the methods of non-resonant inelastic x-ray scattering (IXS) and nuclear resonant scattering (NRS).  IXS provides full access to phonon dispersion in crystalline, disordered, and liquid samples with meV resolution, while NRS provides phonon density of states (DOS) information with unmatched specificity and quality.  These complimentary techniques can be readily applied to small (micron scale) samples, as is made easier by the extremely high intensity beams available at SPring-8 due our specialized insertion devices.   In addition, NRS includes spectroscopic techniques with ~neV resolution that may be used to investigate both slow atomic motion and hyperfine levels, and may also be applied to probe more fundamental physical properties.   Most work is now done at BL09XU and BL35XU, with occasional work at other beamlines, but the programs will move predominantly to BL35XU in 2021.  We, in collaboration with SPring-8 users, are happy to apply established methods to new samples and problems, and also to further develop advanced techniques.  New users, especially, are encourage to investigate the opportunities made possible using the methods supported by the Precision Spectroscopy Division.
