RESONANCE ABSORPTION OF NUCLEAR GAMMA RAYS AND THE DYNAMICS OF ATOMIC MOTIONS
The theory of resonance absorption of nuclear gamma rays is generalized for an arbitrary system of interacting particles by expressing the relevant transition probability in terms of a space-time self-correlation function; thus relating the resonance line shape to the incoherent differential scattering cross section for slow neutrons. Two limiting cases, a gas and a solid, were considered. Discussion regarding the justification of the use of a classical self-diffusion function for a liquid is given, and expressions for the broadening of the resonance line due to diffusive motions of the atoms of the interacting system are derived. It is suggested how Mossbauer-type experiment could be used to give information regarding the diffusive motions of atoms in a solid and also, under more favorable circumstances, in a liquid. (auth)
