title: Refinement in quantitative convergent beam electron diffraction (QCBED).
abstract: Quantitative convergent beam electronic diffraction (QCBED) method is a powerful tool for the investigation of the atomic and electronic structure of crystals. In this work, a global optimization algorithm has been adopted and a new fitting manner has been suggested in our recently developed QCBED program. A study of the charge density distribution in intermetallics is demonstrated as an example. Using the QCBED method, an investigation of lattice distortion in oxides is attempted.
