摘要：

Mossbauer spectroscopy using synchrotron radiation has previously been Limited by the presence of a large non-resonant radiation background which dominates the detector performance and in turn limits the useable incident flux. In this paper we show that it is possible, by using the polarization properties of hyperfine-split Mossbauer resonances in conjunction with a perfect-crystal polarimeter, to completely remove this limitation for enriched samples. For samples with natural isotopic abundance, signal-to-noise ratios close to unity are demonstrated.
