Systematic Absences of the magnetic space group Pc'a21' (#29.101) in the setting (a, b, c; 0, 0, 0) of the parent space group Pca21 (No. 29)


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 0 l)     ->      Systematic absence:    l = 2n + 1

For  l = 1 :      I = 0       F = (0,0,0)
For  l = 2 :      I /= 0       F = (0,Fy,0)

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