Abstract
Low-angle X-ray diffraction patterns have been recorded from normal nerve and nerve swollen in glycerol solutions. The new X-ray data have a resolution of 7 A. Direct methods of structure analysis which include deconvolution of the auto-correlation function and sampling theorem reconstructions have been used in the interpretation of the X-ray data. Phases have been assigned to the first 12 orders of diffraction from normal nerve. Fourier syntheses at a resolution of 7 A are described and an absolute electron density scale is derived. A possible molecular interpretation of the electron density profile is given.
摘要
已记录了来自正常神经和在甘油溶液中肿胀的神经的低角度X射线衍射图谱。新的X射线数据分辨率为7埃。在对X射线数据的解释中使用了包括自相关函数反卷积和采样定理重建在内的直接结构分析方法。已为正常神经的前12个衍射级分配了相位。描述了分辨率为7埃的傅里叶合成，并推导了绝对电子密度标度。给出了电子密度分布的一种可能的分子解释。
