Conversion electron Mossbauer characteristics

Mossbauer transitions are usually highly converted and are followed by the emission of characteristic X-rays and Auger electrons. (The total internal conversion coefficient is high. For most cases de-excitation of the nucleus is via the emission of conversion electrons followed by rearrangement of the excited atomic shell by X-ray emission and Auger processes. More than one electron is produced per resonant scattering event.) The detection of electrons has proved in many cases to be the most efficient means... 

The variables describing electrons and nuclei are termed electronic and nuclear. For the majority of problems which arise in chemistry, the nuclear variables can be thought to be the Cartesian coordinates of the nuclei in the physical three-dimensional space. Of course the nuclei are in fact inherently quantum objects which manifest in such characteristics as nuclear spins - additional variables describing internal states of nuclei, which do not have any classical analog. However these latter variables enter into play relatively rarely. For example, when the NMR, ESR or Mossbauer experiments are discussed or in exotic problems like that of the ortho-para dihydrogen conversion. In a more common setting, such as the one represented by the...
