Magnetic diffraction Systematic Absences for the group
Pn'a'2
_{1}
(#33.148)
For this space group,
BNS and OG settings
coincide.
Its label in the OG setting is given as:
Pn'a'2
_{1}
(#33.5.230)
Values of h, k, l:
h integer, k integer, l integer
Systematic absences for special reflections:
Diffraction vector type:
(0 0 l)
-> Systematic absence:
l = 2n
For l = 1: I /= 0 F = (Fx,0,0)
For l = 2: I = 0 F = (0,0,Fz)
[Show form of structure factor for every type of reflection]
