TEXT: The authors consider two cases:
Case 1. The crystal is bounded by the planes y = + I Z = +
7 T
in the x direction the crystal is long compared with the first
Fresnel zone so that it can be assumed to be infinite.
Case Il. The crystal is bounded by x - t A, z - t-2 and infinite
in the y-direction. 2 2
In both oases a plans monochromatic wave falls the crystal in the
direction of a vector situated in the xz-plane. The relative in-
tensity S0/T0 of the reflected waves is calculated, where S and
T are the amplitudes of the reflected and of the incoming hve.
I~ is stated that the relative intensity is essentially smaller
in the second case, e. g. for B or A = 10-3cm the maximum of

the Form of the Reflecting Crystal (case of the Absorbing Crystal)

TEXT: . The paper is a continuation of (Ref. 1) where the same problem was
considered for the case of a non-absorbing crystal. The authors investigate
the dependence of the intensity of reflected Roentgen waves on the
orientatio+f the plane of incidence with respect to a crystal which is un-
bounded in one direction and bounded in two directions. Two cases are con-
sidered t 1) the inciding wave lies in the xz-plane and the crystal is in-
finitely extended (ooA BYC) in the x-direction; 2) th- inciding wave lies
in the xz-plane and the crystal is infinitely extended (AX oo;
