Pressure Dependence of EXAFS Debye-Waller Factors in Crystals

Vu Van Hung, Ho Khac Hieu, Nguyen Van Hung


In present article the pressure dependence of Debye-Waller factors in crystals has been investigated by using statistical moment method and anharmonic correlated Einstein model. These two methods provide similar results which indicate that the Debye-Waller factors of crystals decreases slightly under high pressure. Our numerical results for several crystals are compared to other theoretical and experimental values and showed a good agreement.
