Notes:
Hamilton's equations for secondary extinction are considered in the light of Riemann's integration of the hyperbolic differential equation. It is shown that Green's function for diffraction from a crystal in the Bragg geometry is determined by an integral equation. The equation is valid for an arbitrarily shaped crystal boundary curve as long as the boundary does not become tangent to the incident or diffracted beam directions.
