Intersection of first order Laue zone lines along the [100] direction in an FCC material.
An analytical result is given for the wavelength at which two or more first order Laue zone (FOLZ) lines intersect at a single point on the positive x axis when a face centred cubic crystal is observed in the convergent beam mode with the beam axis parallel to the [100] direction. The position of the intersection along the x axis is also given. The method uses the kinematic approximation of electronic diffraction and the exact hyperbolic form of the FOLZ lines, so that the accuracy is good even for lines that intersect at small angles.
