The structure of anorthite, CaAl₂Si₂O₈. II. Description and discussion

Abstract

large ~ they diverged at small ~. Hence empirical curves were drawn through the observed points, and from the curves for layers 5 and 6 those for the other layers were deduced. The corrected intensities for elongated and contracted reflections were scaled independently, layer by layer, to the calculated structure factors. When the same reflection occurred in both sets, agreement was good, and mean values were finally used.
