Application and Development of Methods of Positron Annihilation Spectroscopy for Definition of the Nature, Concentration and Size of Nanoobjects in Materials and Nanomaterials on Basis of Silicon and Iron. Review

It has been shown that one of the effective methods for determining the size of nanoobjects (vacancies, vacancies clusters), vacant cavities, empty spaces, concentration of chemical composition in annihilation of porous materials is the method of positron annihilation spectroscopy. The article features a brief look at experimental researches of nanodefects in porous silicium, quartz irradiated by proton
