[求助] 请问金属材料的Debye-Waller因子(即温度因子)的数量级

对仅包含一个原子的金属晶体,做XRD分析时,需要用到温度因子,即Debye-Waller因子,其大小或数量级是多少?谢谢!

For inorganic ionic crystals and intermetallic compounds, the typical range of B’s is ∼0.5 to ∼1 A2; for other inorganic and many coordination compounds, B varies from ∼1 to ∼3 A2, while for organic and organometallic compounds and for solvent or other intercalated nonbonded molecules or atoms, this range extends from ∼3 to ∼10 A2

Note: B and U is not in same quantity.
