| Abstract: | In the present work, the defect structure of the single crystals CsI(Na) with different Na concentratration was investigated by means of the low-temperature acoustic spectroscopy. Measurements of the logarithmic decrement δ(T) and the dynamic Young's modulus E(T) were carried out over the temperature interval 2 K < T < 20 K using the two-component vibrator technique. Longitudinal standing waves were excited in the samples along <110> crystallographic direction at the fundamental vibrator frequency f ≈77 kHz, and also at the third and fifth harmonics of the piezoelectric transducer. |
