M ssbauer spectroscopy, based on the recoil-free resonance fluorescence of ? photons observed with certain atomic nuclei, is a powerful investigating tool in most disciplines of natural science ranging from physics to chemistry to biology. This nuclear method makes it possible to measure the energy difference between nuclear energy levels to an extremely high resolution (up to 13 15 decimals). This resolution is required to measure the slight variation of nuclear energy levels caused by electric monopole, electric quadrupole and magnetic dipole interactions between the electrons and the nucleus. M ssbauer nuclides being at different microenvironments act as local probes for the sensitive detection of the hyperfine interactions. Such interactions reflect changes in the electronic, magnetic, geometric or defect structure as well as in the lattice vibrations, serving as a basis for a variety of applications. In this chapter we describe the principles and some practical aspects of M ssbauer spectroscopy.
M ssbauer spectroscopy is based on the M ssbauer effect discovered by Rudolf M ssbauer (M ssbauer 1958a, b). The discovery was honored by the Nobel Prize in 1961.
The M ssbauer effect is the nuclear resonance fluorescence [1] of ? rays. In the case of...
