Abstract

Direct transmission electron microscopic investigations were carried out on colloid-(640 nm) and XK-centres (580 nm) in NaCl crystals. The crystals were checked by optical microscopy as well as by absorption spectroscopy. In samples containing mainly colloids additional reflections could be found in the selected area diffraction patterns. These foreign reflections were attributed to metallic Na particles. The absence of any additional foreign reflection to samples containing mainly XK-centres indicates that in contrast to the colloids the XK-centres do not behave like any foreign phase in NaCl.
