[Congress Report]

Charge density analysis

P. Coppens (New York) gave an overview of experimental aspects and T. Koritsanszky (South Africa) talked about refinement procedures. B. Iversen (Denmark) gave an account of multitemperature studies and surprising behaviour in the ordering mechanism in a mixed valence iron compound. Only at near 10 K did it become possible to determine reliably the charge density distribution.The other speakers, A. Kirfel (Germany), M. Takata (Japan); N. Ishizawa (Japan), and V. Streltsov (Australia) described applications to chemical and physical problems.Results from synchrotron radiation facilities in the USA, Germany, France, and Japan were presented.
