Abstract : In order to gain some perspective on the relationship of the Mossbauer effect to the possible development of gamma ray lasers, it is useful to review the Mossbauer effect literature. These results show that :1) Rayleigh and nuclear resonant diffraction by scattering is small, 3) nuclear anomalous dispersion occurs, 4) interference can occur between nuclear hyperfine components in nuclear resonant diffraction, 5) in nuclear resonant Bragg scattering, processes having different final nuclear spin projections are incoherent, and 6) there can be anomalously deep penetration and high reflectivity using single crystals as a result of the suppression of inelastic channels.
