摘要：

The diffraction of X-rays by a nematic polybenzothiazole fiber produces an intensity distribution in reciprocal space that is a composite of what has been predicted for isolated periodic cylinders and for parallel arrays of infinite cylinders. It consists of periodically spaced disks and equatorial maxima corresponding to a hexagonal packing of cylinders. The number of parallel cylinders comprising coherently diffracting bundles can be estimated by comparing calculated intensity distributions rather than from line-breadth measurements of equatorial intensities. © by Akademische Verlagsgesellschaft, Wiesbaden 1979
