Summary
The Mössbauer effect is well interpreted and understood in an ideal, infinitely stiff (mathematical) lattice. However we argue that the electrostatic forces that are usually considered in solid-state physics are not adequate to support such a «stiffness». This difficulty is seen to been surmounted by a «superradiant» behaviour of the plasma of nuclei of a crystal.
