Abstract

Reexamination of the isomer shift has led us to propose that the phonons in a lattice change the electron density at the site of the resonant nucleus, thereby causing a change in the energy of the emitted

γ

photon in the recoilless emission of radiation. The new shift is highly temperature dependent and is significantly smaller than the well-known isomer shift. Experimental evidence is presented.
