TIME EVOLUTION OF INCOHERENT-SCATTERING UNDER DOUBLE GAMMA-NMR RESONANCE CONDITIONS

Incoherent Mossbauer scattering under the condition of double gamma-NM R resonance is considered. A radio frequency field mixes the hyperfine sublevels of a nucleus. Thus, quasi energy splitting in the rotating frame takes place. Time dependencies of the intensity of scattered rad iation have been analysed both under the CEMS condition and in the reg ime of Mossbauer spectroscopy with synchrotron radiation.
