Mössbauer diffractometry on polycrystalline 57 Fe 3
A Mössbauer powder diffractometer was used to measure diffraction patterns from polycrystalline foils of Fe3Al. The intensities of Bragg diffractions were measured as a function of the energy of the incident photon. The bcc fundamental diffractions showed large changes in intensity as the incident energy was tuned through the nuclear resonances. These variations of diffraction intensity with in...

متن کاملChemical Environment Selectivity in Mössbauer Diffraction from 57 Fe 3
T. A. Stephens and B. Fultz Division of Engineering and Applied Science, mail 138-78, California Institute of Technology, Pasadena, California 91125 (Received 5 March 1996) Mössbauer diffraction was used to measure different autocorrelation functions for 57Fe atoms in different chemical environments. The sample was polycrystalline Fe3Al with the ordered DO3 structure. Diffraction peaks from a f...
متن کاملIntensities of Mössbauer diffractions from polycrystalline bcc 57 Fe
Diffraction patterns were measured on a polycrystalline bcc Fe foil using a Mössbauer powder diffractometer with high sensitivity. Measurements with and without a magnetic field normal to the scattering plane showed large differences in the diffracted intensities of the different nuclear resonances. These magnetic effects on diffraction intensities were interpreted successfully with a single sc...
متن کاملMossbauer Spectroscopy of 57 Fe Dennis
Using recoilless Mossbauer spectroscopy methods, we investigate the atomic absorption spectra of the 14.4keV transition in Fe compounds. The natural linewidth of this transition is determined to the correct order of magnitude with χν = .75. Hyperfine energy shifts in iron oxide and iron sulfate are investigated and measured. The ratio of ground and excited state magnetic moment in Fe is found t...
