Neutron and Raman Scattering Studies of Hgba₂CuO_4+δ

The HgBa₂CuO_4+δ sample was characterized by Neutron diffraction and magnetic measurements. Both of the measurements indicate a high purity of the sample. Raman measurement was performed on a HgBa₂CuO_4+δ compound ...

Quasielastic gamma-ray scattering from glycerol

The Mössbauer scattering instrument at the Missouri University Research Reactor (MURR) has been used to study the liquid dynamics of glycerol as a function of temperature. The measurements were made by observi...

Mössbauer spectra obtained by modulation of a scattering crystal

We have carried out numerous experiments with supersources having intensities in the 100 Curie range. These sources usually require massive shielding, and are not easily moved to carry out Mössbauer spectrosco...

Asymmetry parameters in¹⁸³W and¹⁸²W using mice detection with a crystal monochromator

Using exceptionally high intensity Mössbauer sources (∼ 1–100 Ci) of¹⁸²Ta and¹⁸³Ta, we have measured the Mössbauer effect for the 46.5 and 99.1 keV transitions of¹⁸³W and the 100.1 keV transition of¹⁸²W. Using a ...
