Among all the elements Sn¹¹⁹ is one of the very useful isotopes for investigating the physical and chemical properties of crystals by means of Mössbauer Spectroscopy. A general discussion of the basic experiments are provided in the first four chapters. In addition, a "standard isomer shift" and a "characteristic factor of bonding" have been defined; the latter is useful for studying the electronic structure of the crystal. The apparatus available for Mössbauer experiments at the Department of Physics, Northern Illinois University, is outlined in Chapter V. The author’s designs of a Mössbauer furnace and a velocity transducer has been introduced in this chapter. CeSn₃ is one of the tin compounds whose electronic structure is a very complicated function of temperature. Tsuchida et al. pointed out that the magnetic susceptibility at low temperatures deviated from the normal Curie-Weiss behavior. This deviation was considered as due to the transformation of 4f electrons of cerium atoms. It is the purpose of this experiment to investigate the possible change of electronic structure of the tin atom in CeSn₃ matrix which reflects the change of magnetic properties in the crystal at different low temperatures.
