Systematic Absences of the magnetic space group P21' (#4.9) in the setting (3b, -a, c; 0, 1/4, 1/4) of the parent space group Pnma (No. 62)

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

Warning: h, k, l are referred to the parent-like setting

Systematic absences for special reflections:

Diffraction vector type:   (0 k 0)     ->      Systematic absence:    k = 2n + 1

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

[Show form of structure factor for every type of reflection]
