Use of 44Ti in the time-differential γγ perturbed-angular- correlation method for studying condensed matter

The principal aspects of 44Ti application in time-differential γγ perturbed-angular-correlation method (TDPAC) for studying condensed matter are discussed. In the presented spectrometer modification, the efficiency of 44Ti application can be considerably increased by using thin NaI scintillator crystals. Promising techniques for 44Ti production and a method for synthesizing samples are described. Examples of TDPAC studies of titanium (rutile TiO2) and scandium (Sc2O3) oxide samples are shown.
