Experimental demonstration of time-integrated synchrotron-radiation spectroscopy with crossed polarizer and analyzer

We present the results of a successful experiment performed with time-integrated synchrotron-radiation spectroscopy, a technique for studying hyperfine interactions. The measurement was performed on an enriched Fe sample in combination with a stainless-steel reference. A crossed polarizer/analyzer was used to reduce the prompt count rate. Time-integrated synchrotron-radiation spectroscopy is compared to the existing time differential synchrotron-radiation spectroscopy. The use of the polarizer/analyzer setup is discussed. Possible applications of time-integrated synchrotron-radiation spectroscopy are mentioned.
