The research described in this report studies the temperature dependence of the change of the local magnetic field near a Xenon atom due to interatomic interactions. Higher order cluster effects, anharmonic contributions in the solid phase and an improved treatment of the exchange interaction are considered. Further studies include the strain dependence of the Helmholtz free energy up to second order as well as first and second order temperature derivatives. We have thus been able to understand the magnitude of the anharmonic contributions, for a simple model potential, to elastic constants, the specific heat, entropy etc. The theory of the temperature dependence of the Debye-Waller factor obtained from Mossbauer experiments has been presented.
