Abstract

The first part of the paper gives a general equation for triple-crystal arrangement with perfect crystals on the assumption that the third crystal is rotated. It is shown that in the case of perfect crystals the shape of the reflection curve is practically independent of the vertical divergence. The case of mosaic crystals is also solved and the possibility of rotation by other than the third crystal is considered. A method is proposed for investigating the imperfection of a crystal which is different from methods used up to now. The paper is supplemented by some experimental results.

Abstract

В первой части статьи дается общее уравнен ие для трехкристальной уст ановки с совершенным и кристаллами при усло вии, что поворачивает ся третий кристалл. Показано, что в случае совершен ных кристаллов форма кривой отражения практичес ки не зависит от вертикальной диве ргенции. Далее, решен с лучай с мозаичными кристалл ами и кратко обсуждается возможность поворот а другим кристаллом, кроме тре тьего. Предлагается метод и сследования несовер шенства кристалла, отличный о т уже существующих методов. Статья допол нена некоторыми экспериментальными результатами.
