He is a physicist who has just finished his PhD thesis and started to work for Infineon. He developed conversion electron Mössbauer spectroscopy (CEMS) on 57Fe and 197Au for routine measurements. Depth selective studies of surfaces can be performed also by applying backscattering Mössbauer spectroscopy. The depletion of silver and copper from the surface of Celtic gold coins during burial is studied using Mössbauer spectroscopy on 197Au. First studies of surface treatments of Formative sherds are underway using CEMS and backscattering Mössbauer spectroscopy. The results can then be compared with transmission Mössbauer measurements of the bulk material. He enjoyed practical work and did some field experiments in casting of replica Celtic coins.
