Abstract: This chapter describes the basic principles of the Mössbauer effect and discusses the hyperfine interactions registered in Mössbauer spectroscopy and practical aspects of the use of exotic Mössbauer isotopes. In γ-radiation resonance absorption we need two nuclei: an excited nucleus emitting a γ quantum with energy E0 and the nucleus of the same isotope in the ground state absorbing this quantum. It is possible only if the emitted γ quantum has energy E0 with uncertainty on the order of Γ0. For nuclear transitions this effect exists only for specific conditions. Mössbauer spectroscopy has made important contributions to the determination of oxidation numbers, local bonding symmetry, and magnetic structure in many crystalline and amorphous solids, and it is broadly used in both industry and research. However, the essential disadvantage of the method is its restriction to a few suitable nuclear isotopes.
