Popis:	Photoinduced changes in thin films from the Se-Ag-I system are investigated firstly, employing various methods-holography, microscopy, electron microscopy, X-ray analysis, and Auger electron spectroscopy. The influence of the composition on the photoinduced changes, as well as the possibility of inducing considerable photoanisotropy, is demonstrated. The mechanism of the processes is discussed on the basis of the experimental data, the phenomena being related to Weigert effect in silver halide system, photocrystallization, and orientation of defects in chalcogenide systems. 14 refs., 8 figs.
