119Mößbauer-Spectroscopy for glasses

The basis of Mößbauer spectroscopy is the simultaneous observation of the Doppler and recoil-free Mößbauer effect. In the case of the Mößbauer effect g -radiation is emitted or absorbed by the nucleus. If the nucleus is being moved mechanically during the process of radiation, a modulation of the emitted wavelength will occur (Doppler-effect). When nuclei are irradiated with this modulated radiation conclusions can be drawn from the transmission spectra whether and how much of a certain element is present.

In our working group we use this method to investigate the procedures during the float process, which is used in glass making. Of special interest is tin, which is diffusing into the glass during the float process. The project is being financed by the Schott AG.
