ABSTRACT
Ten years ago it was proposed that the Gamma Ray Induced Doppler broadening (GRID) method could be used to study interatomic potentials in solids. Recently, this possibility was developed into a powerful technique due to the combination of Molecular Dynamics simulation techniques with the use of oriented single crystal targets. A systematic study of interatomic potentials in metals will be presented. High quality Crystal-GRID data on pure Ni, Fe and Cr were obtained using the GAMS4 spectrometer at the High Flux Beam reactor of the Institut Laue Langevin in Grenoble (France). Fits of the pronounced fine structures on the measured lineprofiles permitted the verification of several interatomic potentials proposed for these metals as well as the extraction of a new interatomic potential. An outlook to further applications in solid state physics of this technique is also presented. © 2000 American Institute of Physics.
