- 論文の詳細を見る
A synchrotron-radiation-based neV-resolution spectrometer has been developed using single-line pure nuclear Bragg reflection. The developed optical system consists of two components: a 57FeBO3 single crystal near the Néel temperature for producing 57Fe Mössbauer radiation from synchrotron radiation, and a single-line Mössbauer absorber (57Fe-enriched stainless steel foil) for analyzing the energy distribution. As a feasibility study, we have performed the measurement of the Mössbauer radiation diffracted by a Si crystal under ultrasound vibration with the optical system and have successfully observed the neV-range energy modulation due to the ultrasound vibration.
