## Magnetic diffraction Systematic Absences for the group P4/m'b'm' (#127.395)For this space group, BNS and OG settings coincide.Its label in the OG setting is given as: P4/m'b'm' (#127.9.1061)

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

#### Systematic absences for special reflections:

Diffraction vector type:   (h 0 0)     ->      Systematic absence:    h = 2n

`For h = 1:      I /= 0       F = (0,Fy,0)`
`For h = 2:      I = 0       F = (Fx,0,0)`

Diffraction vector type:   (0 k 0)     ->      Systematic absence:    k = 2n

`For k = 1:      I /= 0       F = (Fx,0,0)`
`For k = 2:      I = 0       F = (0,Fy,0)`

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

`For l = 1:      I = 0       F = (0,0,Fz)`
`For l = 2:      I = 0       F = (0,0,Fz)`

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

`For h = 1:      I = 0       F = (Fx,-Fx,0)`
`For h = 2:      I = 0       F = (Fx,-Fx,0)`

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

`For h = 1:      I = 0       F = (Fx,Fx,0)`
`For h = 2:      I = 0       F = (Fx,Fx,0)`
