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

Аннотация

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.
