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
