We have developed a new method that yields Mssbauer absorption spectra using synchrotron radiation (SR); this method is applicable for almost all Mssbauer nuclides including those that cannot be measured by previous methods using radioisotope (RI) sources. The Mssbauer spectrum of the 68.752 keV excited state of 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 Mssbauer spectroscopy measurements owing to the excellent features of SR.
