A simple description is given of the change in the state of a crystal lattice upon emission or absorption of a nuclear gamma ray. A sum rule is derived for the average energy transfer to the lattice. The probability of zero energy transfer is calculated. The results are general and do not assume a p

The structure is related to that of so-called \
## Abstract SnO~2~–Fe~2~O~3~ nanopowders prepared by the polymeric precursor method were studied by combined conventional and high‐resolution techniques. The powders treated at 500 °C were analyzed by EDS local probe associated with HRTEM to directly detect surface segregation of Fe ions onto SnO~2
