Extinction rules for the group P_c31m (157.56)




Extinctions for general positions (produced by centrings):

   (h k l)     ->      Extinction rule/s:    l = 2n
    For  h = 1, k = 1, l = 1 :      I ≠ 0       F = (Fx, Fy, Fz)
    For  h = 1, k = 1, l = 2 :      I = 0       F = (0, 0, 0)


Extinctions for special positions:

   (0 0 l)          ->      Extinction Rule/s: l any

   (h -2*h l)          ->      No extra extinctions found

   (2*h -h l)          ->      No extra extinctions found

   (h h l)          ->      No extra extinctions found
