An automated deconvolution of the Patterson synthesis by means of a modified vector-verification method. Its application to some heavy-atom Patterson functions

A general scheme for the deconvolution of the Patterson-vector map is discussed, in which no structural information is needed. It appears to be possible to overcome the difficulties arising from vector overlap and vector coincidence. The vector-verification method is extended so as make it possible to locate every configuration of a small, fixed number of atoms, for which the complete corresponding vector set is present in the Patterson function. A criterion is defined which expresses the reliability of each configuration, making it possible to recognize the correct one.
