Magnetic diffraction Systematic Absences for the group Fd-3m' (#227.131) For this space group, BNS and OG settings coincide. Its label in the OG setting is given as: Fd-3m' (#227.4.1631)

Values of h, k, l: h integer, k integer, l integer

Systematic absences for general reflections (produced by centrings):

Diffraction vector type: (h k l) -> Systematic absence: h + k = 2n + 1 or h + l = 2n + 1

Systematic absences for special reflections:

Diffraction vector type: (h 0 0) -> Systematic absence: h any

For h = 2: I = 0 F = (Fx,0,0)

For h = 4: I = 0 F = (0,0,0)

Diffraction vector type: (0 k 0) -> Systematic absence: k any

For k = 2: I = 0 F = (0,Fy,0)

For k = 4: I = 0 F = (0,0,0)

Diffraction vector type: (0 0 l) -> Systematic absence: l any

For l = 2: I = 0 F = (0,0,Fz)

For l = 4: I = 0 F = (0,0,0)

Diffraction vector type: (h h h) -> Systematic absence: h any

For h = 1: I = 0 F = (Fx,Fx,Fx)

For h = 2: I = 0 F = (Fx,Fx,Fx)

Diffraction vector type: (h h -h) -> Systematic absence: h any

For h = 1: I = 0 F = (Fx,Fx,-Fx)

For h = 2: I = 0 F = (Fx,Fx,-Fx)

Diffraction vector type: (h -h -h) -> Systematic absence: h any

For h = 1: I = 0 F = (Fx,-Fx,-Fx)

For h = 2: I = 0 F = (Fx,-Fx,-Fx)

Diffraction vector type: (h -h h) -> Systematic absence: h any
