Extinction rules for the group Pbcm (57.377)

Extinctions for general positions (produced by centrings):

   Primitive unit cell: No extinctions

Extinctions for special positions:

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

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

    For  k = 1 :      I ≠ 0       F = (0, 0, Fz)

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

(0 0 l) -> Extinction rule/s: l = 2n

    For  l = 1 :      I ≠ 0       F = (Fx, 0, 0)

    For  l = 2 :      I = 0       F = (0, 0, 0)

   (0 k l)          ->      No extra extinctions found

   (h 0 l)          ->      No extra extinctions found

   (h k 0)          ->      No extra extinctions found
