Properties and Behavior of Iron Oxides as Determined by Mössbauer Spectroscopy

Abstract

During the decay of excited nuciear states, γ-rays are emitted which typically have energies that lie in the keV to MeV range. Because of these high energies, nuclei experience a significant impulse during emission and absorption of γ-quanta, i,e., they can recoil to a certain extent, and the γ-ray energy will change accordingly.
