ResumoAbstract A correction procedure for the delocalization effect when determining the site occupancy of an impurity element by atom location by channelling-enhanced microanalysis is proposed. The procedure utilizes a disordered structure with a composition similar to the ordered structure. Correction factors are derived by illuminating a sample with a disordered structure in the same orientation as for the ordered structure. The correction procedure is applied to a determination of the Ti occupancy in a Ni3Al intermetallic compound.
