Extinction rules for the group P_bnma (62.451)




Extinctions for general positions (produced by centrings):

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


Extinctions for special positions:

   (h 0 0)          ->      No extra extinctions found

   (0 k 0)          ->      No extra extinctions found

   (0 0 l)          ->      No extra extinctions found

   (0 k l)          ->      No extra extinctions found

   (h 0 l)          ->      No extra extinctions found

   (h k 0)          ->      No extra extinctions found
