Abstract

It is well known that lattice vibrations generated inside a crystal by an external source of hypersound result in a drastic transformation of the γ-ray spectrum.¹ The hypersound modulation phenomena involving Mössbauer radiation were intensively investigated in the 1970’s both theoretically and experimentally (see, e.g., Refs. 2 and 3 for review articles). However, hypersound coherency-dependent effects in the process of radiative decay of excited states of nuclei in solids have not been sufficiently studied.
