Mössbauer Spectrometer

Mössbauer spectroscopy is a technique that relies on the resonant emission and absorption of gamma-ray photons by atomic nuclei in a solid without energy loss due to nuclear recoil.

The energy levels of an atomic nucleus are perturbed through its interactions with the surrounding environment.

By measuring small changes in the energies of nuclear levels, Mössbauer spectroscopy allows for the use of atomic nuclei as probes for their immediate molecular environment. Among all Mössbauer active elements, owing to its biological and technological importance as well as relative ease with which the experimental spectra can be collected, Iron is the most intensively investigated.
