‘Extra’ Rings and Bands in Electron Diffraction Patterns

SO-CALLED extra or forbidden rings have been observed from time to time in electron diffraction patterns, and their origin has been attributed to half-order diffractions or impurities. Cases in which ...

Extra Rings in Electron Diffraction Patterns

MARK, Motz and Trillat 1 have shown that traces of grease can give rise to extra rings in electron diffraction patterns from metal films. In agreement with them, we have found that the spacings of ...
