Pyroxenes are a major group of rock-forming minerals. Scientists investigated the iron ion status of a calcium-rich pyroxene, using Mössbauer spectroscopy on thin sections of single crystals. The ...

Detectors positioned equidistantly at a distance d from the source are capable of sensing vertical displacements of the Mössbauer resonance point. In the subfigure (lower right), a detector is placed ...
