Abstract:

Defects or impurities have nuclei for which a Mossbauer effect has been observed. Since such nuclei are not light nuclei, one would not ex pect to find them in host crystal composed of isotopes of much greater relative mass, as would be necessary, in three dimensions for the ap pearance of a localized mode. These impurities would therefore be more correctly described as being connected to their neighbors by forces which are not of the same strength as those between host atoms. But, in considering the detectability of LMs by means of the Mossbauer effect, we may deal only with the isotopic case, because the relevant cross section depends upon the spatial attenuation of the LM, which a wide range of force constants will maintain.
