“…I n such a situation a scan of scattered count rate against angle displays no Bragg peak if the source is vibrated hard, whilst a Bragg peak does appear if source and scatterer are on resonance. Good examples of pure Mossbauer diffraction have since been obtained by Smirnov et a1 (1969a, b, c) and Smirnov et al (1970b) using enriched single crystals of a-FeZ03, by Mirzababaev et al (1971) using crystals of sodium nitroprusside, and by Zasimov et al (1972) and Zasiinov and Kuzmin (1975) using the 35.6 keV T e resonance and a single-crystal T e scatterer. I n each of these cases the Rayleigh scattering was zero at an appropriately chosen Bragg reflection.…”

Experimental and theoretical work on the scattering of Mossbauer y radiation by condensed matter is reviewed, covering the period from 1958, and the subject is presented as having features akin to those of x-ray diffraction, inelastic neutron scattering and Mossbauer absorption spectroscopy. An outline of theoretical work on coherence and recoil effects for both electronic and nuclear resonant scattering is given. This is followed by a review of experiments on electronic (Rayleigh) scattering covering thermal diffuse scattering in crystals, Debye-Waller factors, soft modes and critical scattering, diffusion phenomena and amorphous materials, and plastic and liquid crystals, and a review of experiments on nuclear resonant scattering covering coherence interference and diffraction, the crystallographic phase problem, magnetic and quadrupole Mossbauer diffraction, dynamic theory and multiple scattering, cooperative excitation, refractive index, time domain experiments, and experiments based on detection of the conversion electrons.

“…Although primarily "curiosities" for chemists, two other developments should be noted. A number of theoretical and experimental treatments have appeared on the subjects of Mossbauer scattering at the Bragg angle (10,65,339,648,650,651,719) and interferen e between nuclear resonance absorption, followed by internal conversion, and photoelectric absorption (5, 324. 391, 487, 507,659).…”

“…The spectrometry of hyperfine interactions can select 57 Fe atoms in specific chemical environments, and the spatial periodicity of the selected 57 Fe atoms can be measured in a Mo¨ssbauer diffraction pattern. Mo¨ssbauer diffraction patterns of polycrystalline samples suffer from low count rates, compared with those of perfect single crystals that have been used for most previous work with Mo¨ssbauer diffractometry (Black and Duerdoth 1964, Smirnov et al 1970, van Bu¨rck et al 1980, Shvyd'ko and Smirnov 1989. Multiple scattering is so strong for perfect single crystals that dynamic diffraction theory (Kagan et al 1968, Hannon and Trammel 1968, Kagan 1999) must be used to interpret the data, however, rendering impractical any attempt to invert single-crystal diffraction patterns to obtain quantitative information on atomic structure.…”
