Texte intégral accessible uniquement aux membres de l'Université de LorraineThis thesis discusses the problems of the model incompleteness and the computational problems at a very high resolution. The model incompleteness does not allow the determination of the exact values of structure factors in order to compare them with experimental data. A statistical approach suggests a new strategy for the refinement. At a very high resolution the usual models of anisotropic atoms cannot describe precisely the experimental diffraction data and are completed by gaussian diffractors placed in these peaks of the residual density. This simplified model is capable to reduce the R and R-free factors and to derive the topological characteristics of the elec...
