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

We present the results of a successful experiment performed with time-integ rated synchrotron-radiation spectroscopy, a technique for studying hyperfin e interactions. The measurement was performed on an enriched Fe sample in c ombination with a stainless-steel reference. A crossed polarizer/analyzer w as used to reduce the prompt count rate. Time-integrated synchrotron-radiat ion spectroscopy is compared to the existing time differential synchrotron- radiation spectroscopy. The use of the polarizer/analyzer setup is discusse d. Possible applications of time-integrated synchrotron-radiation spectrosc opy are mentioned.
