"WebMay 24, 2016 · One method that takes the configuration of a particle into account is the Rayleigh–Gans theory (e.g., Bohren & Huffman 1983). The Rayleigh–Gans theory, or the first Born approximation, is applicable to an arbitrarily shaped particle as long as the particle's refractive index is close to that of a vacuum, i.e., it is optically soft.
