Abstract
An X-ray topographic method for investigating migration of point defects is described as a summary of previous work carried out on self-interstitials in ice. Since the method presented is based on in situ observations of dislocation climb in a thick specimen, the advantages of synchrotron-radiation topography for this method is emphasized. It is shown that the diffusion coefficients of the point defects can be determined as functions of both temperature and pressure.Keywords
