Extinction rules for the group P_a2 (3.4)




Extinctions for general positions (produced by centrings):

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


Extinctions for special positions:

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