Synchrotron radiation 57Fe-Mössbauer spectroscopy using nuclear monochromator
- 62 Downloads
A synchrotron radiation (SR) Mössbauer spectrometer has been developed by using a nuclear Bragg monochromator (NBM). It enables energy-domain 57Fe SR-Mössbauer spectroscopy (SRMS). Doppler-shifted SR-Mössbauer radiation is produced by pure nuclear Bragg reflection (PNBR) from an oscillating 57FeBO3 crystal near the Néel point. In this paper, we describe the optics and its applications, including high-pressure SRMS, grazing incidence SRMS and γ-ray diffraction studies with the Rayleigh scattering of Mössbauer radiation (RSMR) method.
