"Calcite was the primary X-ray diffraction crystal standard for decades, and its cleavage rhombohedron spacing is exhaustively documented in COD and AMCSD at d = 3.035 x 10^-8 cm (within 1.1% of Bragg's 3.07 x 10^-8 cm, where the slight offset stems from Bragg's 1915 Pd K-alpha wavelength estimate of 0.576 A and glancing angle of 5.35° vs the modern 5.55°)." . . . "Proposed test with existing data: From refined calcite (CaCO3, R-3c) crystal structures, compute the interplanar spacing d of the cleavage rhombohedron face {10-14} (indexed as (100) in Bragg's cleavage-rhombohedron axes) and the first-order Bragg glancing angle theta = arcsin(lambda / (2*d)) for the palladium K-alpha line. Compare against Bragg's reported values of theta = 5.35° and d = 3.07 x 10^-8 cm." . "Gemini 4 Argon on bragg1915-06: resolvable-now, resolvability 0.99" . . "dataset-resolvability/0.2.0" .
