NRS (nuclear resonant scattering) is a technique used in solid state physics to determine different properties of atoms and nuclei and their interaction. In NRS an atom and nucleus get excited by synchrotron radiation, because of the broad spectrum multiple hyperfine levels and the nucleus get excited. After this the system will decay and will send out photons. Different hyperfine levels are excited and consequently different frequencies will be emitted coherently. These combine and lead to a temporal pattern in the intesity depending on the nuclear properties and thus NRS is a way of measuring the EQ, MD and the EMS.
