Synchrotron-Radiation-Based Mossbauer Spectroscopy

We have developed a new method that yields Mossbauer absorption spectra using synchrotron radiation (SR); this method is applicable for almost all Mossbauer nuclides including those that cannot be measured by previous methods using radioisotope (RI) sources. The Mossbauer spectrum of the 68.752 keV excited state of (73)Ge, which cannot be measured using a RI source, was measured using SR. Our results show that this method can be used to perform advanced Mossbauer spectroscopy measurements owing to the excellent features of SR.
