Debye - Waller factor measurements of solid 3 He and 4
X-ray synchrotron radiation was used to measure Debye-Waller factors of helium crystals for both He and He in both hcp and fcc phases. To our knowledge, there are no previous measurements for He. The ranges studied for He and He crystals were 11.52–12.82 and 10.95–12.13 cm, respectively, and 11.5–18.2 and 12.0–20.3 K. With small uncertainty, only a Gaussian dependence upon momentum transfer Q w...
متن کاملOn EXAFS Debye-Waller factor and recent advances.
The effects of structural and vibrational disorder on the EXAFS signals are parameterized in terms of the Debye Waller (DW) factor. Here the vibrational contribution is addressed, which for most systems can be singled out by studying the temperature dependence of the EXAFS DW factor, which corresponds to a good accuracy to the parallel mean square relative displacement (MSRD) around the inter-a...

متن کاملTemperature Variation of Debye-Waller Factor for Alkali and Noble Metals
Debye-Waller factors at different t empera tures of four alkali and three noble metals have been computed on the basis of a screened shell phenomenologica l model . T h e theoretical values are compared with existing experimental data . Part icularly for l i th ium and potassium, most recent experimental information has been included. A critical examina t ion of the results reveals a satisfacto...
متن کاملDebye–Waller coefficient of heavily deformed nanocrystalline iron1
Synchrotron radiation X-ray diffraction (XRD) patterns from an extensively ball-milled iron alloy powder were collected at 100, 200 and 300 K. The results were analysed together with those using extended X-ray absorption fine structure, measured on the same sample at liquid nitrogen temperature (77 K) and at room temperature (300 K), to assess the contribution of static disorder to the Debye-Wa...
