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".
