Masuda, Ryo; Mitsui, Takaya; Kobayashi, Yasuhiro*; Higashitaniguchi, Satoshi*; Seto, Makoto

A neV-resolution spectrometer using 14.4 keV synchrotron-based $^{57}$ Fe Mssbauer radiation has been developed to observe the quasi-elastic scattering by condensed matter. It consists of a $^{57}$ FeO nuclear resonant Bragg monochromator and a $^{57}$ Fe stainless steel nuclear analyzer. As a feasibility study, the quasi-elastic scattering by supercooled glycerol near its melting point has been observed. The instrumental function of the spectrometer was 42.2 neV. The energy broadening of 11 neV due to the quasi-elastic scattering was observed.
