Extinction rules for the group P4/m'nc (128.401)

Extinctions for general positions (produced by centrings):

   Primitive unit cell: No extinctions

Extinctions for special positions:

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

   (h 0 0)          ->      Extinction rule/s:    h = 2n + 1

    For  h = 1 :      I = 0       F = (Fx, 0, 0)

    For  h = 2 :      I ≠ 0       F = (0, Fy, 0)

(0 k 0) -> Extinction rule/s: k = 2n + 1

    For  k = 1 :      I = 0       F = (0, Fy, 0)

    For  k = 2 :      I ≠ 0       F = (Fx, 0, 0)

   (h h 0)          ->      No extra extinctions found

   (h -h 0)          ->      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

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

   (h h l)          ->      No extra extinctions found
