A systematic method for unravelling a periodic vector set
Masayasu Tokonami, Shinichi Hosoya · Acta Crystallographica · 1965
A new method is presented for unravelling a periodic vector set.This method, being entirely different from the image seeking method or its variations, makes full and systematic use of periodic characters involved in a periodic vector set.The details of unravelling procedures are systematically described.The procedures are illustrated in a simple case, and further it is shown that the proposed procedures are really effective for unravelling vector sets corresponding to several hypothetical and real structures.In some examples, the computations including logical operations are carried out on an electronic computer.Some characteristics of the present method are discussed.General aspects of the phase problem are also described from a standpoint reached through the present work.
