The Mossbauer effect is discussed and applied to nuclear resonance fluorescence measuremerts previously thought to be impossible. Mossbauer discovered that if nuclei are bound in a solid at low temperatures there may be an appreciable probability that the gamma rays will be emitted without either the energy shift due to the recoiling nucleus or the energy broadening due to the crystal. Thus, the emission and absorption take place without energy exchange between the nucleus and the lattice, and the recoil momentum is taken up by the zero point motion of the whole crystal, rather than by a single nucleus. The resonance spectrum is discussed with regard to line intensity and shape, chemical and temperature shifts, electric hyperfine structure, and magnetic hyperfine splitting. Results are preserted of studies of lattice vibrations in crystals and measurements of hyperfine fields in ferromagnets. (N.W.R.)
