摘要
本文是在讨论L—B膜中各个原子的单原子散射效果的基础上,考虑各个原子散射效果的迭加得出多原子系统的散射效应,结合具体情况加以修正来计算MnSt_2L—B膜的精细结构。其结果与文献报道实验一致,并给出了Mn^(2+)相对于Coo^(-1)的位置,Y型L—B膜的层间距等新结果。
X-ray scattering from each atom contained in L—B films is invesigated. The average sum of single-atomic scattering gives the scattering of multi-atomic system. The method modmed on basis of experimental data is used to study the fine structure of MnSt_2(St: stearate) L—B film. The results obtained are consistent with those reported in literature. The position of Mn^(2+) related to Coo^(-1) group of stearate in the monolayer and the interlayer distance between two hydrophilic surfaces of MnSt_2 Y-type films are examined for first time by this meth
