NOTE:Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. The effects of the atomic electrons on nuclear gamma emission are considered. It is found that the electrons, excited by the nuclear electrostatic field, can emit gamma rays coherently with the nucleus and thus add to the observed intensity of radiation. The correction is computed for K electrons, for electric dipole and quadrupole radiation, and is found to be small, of the order of a few per cent, for energies equal to the K binding energy. It drops rapidly with increasing energy, varying inversely as the square of the gamma ray energy. The Z-dependence of the effect is essentially Z[superscript negative 1]. For gamma ray energies corresponding to electron transitions between bound levels large resonances may occur, but they are of narrow width and their observation would be fortuitous.
