Abstract
It is demonstrated for the example of tetragonal tungsten bronze that it is possible, as was indicated in a previous paper [V. L. Indenbom and S. B. Tochilin, JETP Lett. 65, 252 (1995)], to resolve to within 0.2–0.3 Å the atomic columns along which electrons are channeled. The-Nb-O-Nb-columns are represented by 1S Bloch waves with a half-width of the order of 0.1 Å and the-W-O-W-columns are represented by 2S Bloch waves, which give aureoles with diameters of the order of 1 Å. A chemical analysis of the sample is performed on the basis of the brightness of the peaks in the Patterson map.
