Abstract
Synchrotron radiation Mössbauer spectroscopy was performed using a pure nuclear Bragg reflection of a 57FeBO3 single crystal at the Néel temperature and a Bragg reflection of an oscillating Si single crystal. The developed optical system for nuclear diffraction could produce a Doppler-shifted 14.4 keV single-line 57Fe-Mössbauer radiation and it enabled us to observe the energy-domain synchrotron radiation Mössbauer spectrum with an absorber at rest.
