Triple-crystal X-ray spectroscopy of diffuse scattering from tracks

A theoretical model is presented for studying the structure of tracks of ch arged particles in crystals. Two structurally different track regions are c onsidered: the track proper and its elastically deformed vicinity. A comput er program is written for determining the contributions from a track and it s elastically deformed vicinity to the experimental diffuse-scattering data and their quantitatively evaluating dimensions and other parameters. The e ffect of the model parameters on the shape of diffuse-scattering curves is also considered. (C) 2001 MAN "Nauka/Interperiodica".
