educational work of group. Within the framework of laboratory courses "the physical practical work " and " physical bases of the information reception" for 3 years students of physical and engineering specialities were carried out laboratory works by a technique of x-ray researches of fullerites and carbon black containing fullerenes. Opportunities of information reception on crystal structure of fullerites of various structure were analyzed. Within the framework of a laboratory practical work for 4 years students for courses " Methods of diffraction researches of materials " and " Computer processing of results of diffraction experiment " were carried out laboratory works: "Rietveld analysis of the x-ray pattern of fullerite С60 " and " X-ray pattern indexing of fullerites of various structure ". Are handed over in publishing house PetrSU the textbook: Aleshina L.A., Shivrin O.N. " X-ray analysis of crystals " and the manual for of 3-rd years students at the course Physical bases of information reception: Malinenko V.P., Aleshina L.A., Iljin A.M. «the Physical phenomena and effects for reception and transformations of the information. »

On the one hand, this analysis is necessary to make search of optimum conditions of plasmachemical influences more realized and purposeful, on the other hand, it is extremely interesting to find out behaviour of the materials structure, exposed to so strong influences as a result of which occurrence of new compounds and substances is possible. Structural identification of substance, in itself, represents the complex(difficult), labour-consuming research problem demanding special preparation of samples, the techniques of experiment based on diffraction of x-ray radiation, and application of a complex of mathematical methods for decoding an observable of scattering pattern. The analysis of products of plasmachemical influences on materials is complicated also that, as a rule, samples represent not single-phase objects containing in both polycrystalline phases and an amorphous component. Such work demands not only uses of traditional, standard techniques of research, but also development of new approaches to the analysis of structure of substance in the condensed condition.
