Abstract
This paper gives a brief review of recent X-ray topographic studies on point defects in ice. The self-diffusion mechanism, vacancy mechanism vs. interstitial one, has been one of the long debated problems in ice physics. Recent X-ray topographic observations of dislocation loops formed by heat treatment have revealed that the predominant point defect in ice is a self-interstitial at least above -50°C and that the self-diffusion in ice is caused by migration of self-interstitials through ice lattice. All the interstitial parameters so far obtained by the X-ray topographic methods are summarizedKeywords
