Abstract : The work described in this report has resulted in (1) the development of the theory of light scattering by various crystal imperfections, (2) the production of computer programs for the calculation of light scattering functions, (3) the computer tabulation of specific values for scattering factors or amplitude functions, intensity functions and Mie coefficients as a function of various selected angles of scattering from 0 to 180 degrees and various sizes of spherical voids from 10 to 10,000 A radius, (4) specific tables of the functions of pi and tau occurring in Mie's theory for light scattering calculations, and (5) an engineering design of an optical system utilizing a continuous laser for observing, evaluating, recording and determining the arrangement of defects in crystals.
