Mössbauer spectroscopy

With everything you learned in the previous videos, it is now straightforward to turn nuclear resonant scattering in a useful spectroscopy. You will understand how the different types of hyperfine interactions lead to a characteristic Mössbauer spectrum. And conversely, you’ll understand how to interpret a given (experimental) Mössbauer spectrum.

There is some optional material for this chapter, where you can dig deeper if you want. But first the task: The video shows an example of a Mössbauer spectrum for a magnetic hyperfine interaction, measured at 200, 50 and 18 K. This series of spectra shows that a magnetic field gets established if temperature drops. At 50K, you see the first traces of the field being present. Is that hyperfine field smaller or larger than the field at 18 K? How would you describe what happens inside the sample if you go from 50 to 18 K?
