General :

Nuclear gamma-resonance (Moessbauer) spectroscopy defines the name and topics of scientific activity of the laboratory. Investigations have been conducted in the two main directions corresponding to the particularities of the techniques used. The conventional transmission variant of Moessbauer spectroscopy gives an opportunity to establish a number of physicochemical properties of elements and their compounds in the solid state: valency, covalency of chemical bonding, coordination of ions, distortions in the crystal lattice, presence of several ions in different sites and oxidation states, vacancies, clasters, etc.. The knowledge of all these properties plays an important role in various areas of chemistry. The second topic of investigations is developed on the basis of emission Moessbauer spectroscopy. The subject of study in this case is the processes of high energy chemistry associated with the creation of electron vacancies in deep shells of the atom. Electronic de-excitation of atoms proceeds via the Auger multiple ionization process. Its chemical consequences depend on localized self-radiolysis, the ability of accepting the Auger and secondary electrons by the stabilizing atom, photochemical transformation, etc., and may be studied by the above-mentioned technique.
