T1 - The analog computation of dynamic electron diffraction intensities

AU - Johnson, A. W. S.

PY - 1968

N2 - The Cowley-Moodie slice formulation of n-beam electron diffraction has been manipulated to give a set of linear first order differential equations, one per beam, the coefficients of which are proportional to the Fourier coefficients of the crystal potential. The analog solution of these equations gives a vivid demonstration of the interacting processes involved in dynamic scattering and, with modern analog computers, allows an extremely rapid solution, at least two orders of magnitude faster than comparable digital computer calculations. The advantages and disadvantages of the method are discussed and practical example calculations and applications described.
