The results of SANS studies of the structure of nanocluster impurity gel samples, x-ray observations of structural transformations of amorphous powders obtained by the decomposition of heated gel samples are presented, and the possibilities of using these methods to determine the state and structural transitions of such substances are discussed.
Key words: impurity-helium gels, SANS, x-ray diffraction, crystallization, amorphous structures.
