Abstract
We report on the development and characterization of a medium resolution monochromator for synchrotron-based hyperfine spectroscopy at the 73 keV nuclear resonance of 193-Ir. The device provides high throughput of 6*10^8 ph/s in an energy bandwidth of 300(20) meV. We excited the nuclear resonance in 193-Ir at 73.04 keV and observed nuclear fluorescence of 193-Ir in Iridium metal. The monochromator allows for Nuclear Forward Scattering spectroscopy on Ir and its compounds.
