Abstract

The temperature dependence of the intensity and reflecting range of the (200) reflection of X-rays on an aluminium crystal exhibiting strong primary extinction was studied. It was found that the observed temperature dependence cannot be even approximately expressed by the Debye-Waller factor. The reversible change in the system of imperfections in the crystal is suggested and discussed as a mechanism qualitatively explaining the observed phenomena.

Abstract

Была исследована тем пературная зависимо сть интенсивности и шири ны отражений (200) рентгеновских лучей на кристалле алюмини я, обладающего сильной первичной экстинкцией. Оказало сь, что наблюдаемую температурную завис имость нельзя, даже приблизительно, объя снить с помощью факто ра Дебая-Валлера. Привод ится и обсуждается обратимое изменение системы нарушений в к ристалле в качестве механизма, качественно объясня ющего наблюдаемые яв ления.
