Various authors have tried to exploit Harker sections to estimate the moduli and the phases of the one-phase structure seminvariants (s.s.) of the first rank from single crystal data. The estimates are sufficiently accurate if false Harker peaks are absent; therefore, if some heavy atoms are present in the structure, and this last is not too complex, the results are quite satisfactory.

Abstract
Various authors have tried to exploit Harker sections to estimate the moduli and the phases of the one-phase structure seminvariants (s.s.) of the first rank from single crystal data. The estimates are sufficiently accurate if false Harker peaks are absent; therefore, if some heavy atoms are present in the structure, and this last is not too complex, the results are quite satisfactory.File in questo prodotto:
