The integral reflections are the general reflection conditions due to the centering of cells. They are given in the table below:
Reflection condition |
Centering type of cell | Centering symbol |
---|---|---|
None | Primitive | P R (rhombohedral axes) |
h + k = 2n | C-face centered | C |
k + l = 2n | A-face centered | A |
l + h = 2n | B-face centered | B |
h + k + l = 2n | body centered | I |
h + k, h + l and k + l = 2n or: even (‘unmixed’) |
all-face centered | F |
− h + k + l = 3n |
rhombohedrally centered, reverse setting |
R (hexagonal axes) |
h − k + l = 3n |
rhombohedrally centered, obverse setting (standard) |
|
h − k = 3n | hexagonally centered | H |
