Temperature dependence of nuclear forward scattering of synchrotron radiation in α57Fe

Abstract
The resonant forward scattering of synchrotron radiation by Fe57 nuclei was investigated over the temperature range from 9.7 to 1048 K. The temperature dependence of the Lamb-Mössbauer factor and the internal magnetic field were determined from the observed time spectra. The data presented here demonstrate the suitability of the synchrotron technique for precise measurements of these quantities. In addition these results demonstrate in a straightforward way the difference between the x-ray Debye-Waller factor and the Lamb-Mössbauer factor.
