- Title
Reversed de Wolff figure of merit and its application to powder indexing solutions.
- Authors
Oishi-Tomiyasu, R.
- Abstract
Two new figures of merit for powder indexing solutions are proposed: the reversed figure of merit M nRev and the symmetric figure of merit M nSym. These are naturally suggested by the theory underlying the de Wolff figure of merit M n. Nevertheless, M nRev has characteristics opposite to those of M n with regard to sensitivity to impurity peaks and extinct reflections. M nSym has intermediate properties between M n and M nRev. Applications of the new figures of merit to powder indexing solutions and zero-point shift estimation are introduced. All of the figures of merit are available from the powder auto-indexing software Conograph (http://sourceforge.jp/projects/conograph/; http://research.kek.jp/people/rtomi/ConographGUI/web_page.html).
