Abstract
Nuclear Resonant Scattering (NRS) using synchrotron radiation is a natural extension of the traditional Mossbauer Spectroscopy. Due to its unique source properties, NRS working at time domain can not only study the hyperfine interactions and magnetic properties like the traditional Mossbauer Spectroscopy can do at the energy domain, but also give new possibilities to study the thermal dynamic properties of materials through the inelastic nuclear resonant process. In this talk, current status and applications of the NRS studies at Advanced Photon Source, Argonne National Laboratory will be given.
