THE MOSSBAUER EFFECT.
Abstract
The theory of the nuclear Mossbauer effect and its optical analogue is presented. Introductory paragraphs deal with the destruction of resonance fluorescence in case of a freely recoiling nucleus. The partial restoration of resonance by Doppler effect and thermal broadening is outlined. The concept of zero-phonon transitions between bound nuclear states of nuclei embedded in a crystalline lattice is introduced in a simple quantum mechanical language. The classical derivation of the Debye-Waller factor based on the frequency modulation concept is followed by a rigorous quantum mechanical calculation of the zero-phonon transition probability and its temperature dependence. Lipkin's sum rule is discussed. Application of the Mossbauer effect to determine lifetimes of excited states, nuclear quadrupole moments, and the isomeric shifts is shown. The optical analogue in defect solids is described. (Author)
