The problem to find these phases is the phase problem. The present article will treat the following topics. At first the description of the ideal crystal will be given in Chap. B. The underlying principles of this description are the concepts of reciprocal lattice, FOURIER synthesis and sym metry. The evaluation of the intensity will then follow in Chap. C and D. Chap. E is concerned with the phase problem and related topics. Though this article treats the analysis of crystal structures, the fundamental concepts for other structures will here be found too. But these topics, and the experimental methods, will l find their place elsewhere . B. Description of the crystalline state. I. Lattice theory. a) The direct lattice. 8. Introduction. In Sect. 3, a description of the ideal crystal was given: The space, occupied by a crystal, is divided into congruent parallelepipeds, each with the same orientation. This parallelepiped is defined by the three basic vectors, a, band c, drawn from an origin 0 (Fig. 2), and is called the primitive cell. This cell is filled with atoms (or ions), and the | | 出版日期 | Book 1957 | | 关键词 | Korpuskel; Wellen; X-ray; atom; atoms; density; diffraction; diffusion; electron; metals; neutron; optics; scatt | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-45866-8 | | isbn_softcover | 978-3-642-45868-2 | | isbn_ebook | 978-3-642-45866-8Series ISSN 0085-140X Series E-ISSN 2197-4195 | | issn_series | 0085-140X | | copyright | Springer-Verlag Berlin Heidelberg 1957 |
