WebApr 18, 2015 · A widely used approximation in studies relating to small angle differential scattering cross-section of X-rays scattered by interstellar dust grains is the well known Rayleigh-Gans-Debye approximation (RGDA). The validity of this approximation, however, is limited only to X-ray energies greater than about 1 keV. At lower energies, this … Rayleigh–Gans approximation, also known as Rayleigh–Gans–Debye approximation and Rayleigh–Gans–Born approximation, is an approximate solution to light scattering by optically soft particles. Optical softness implies that the relative refractive index of particle is close to that of the surrounding … See more The validity conditions for the approximation can be denoted as: $${\displaystyle n-1 \ll 1}$$ $${\displaystyle kd n-1 \ll 1}$$ $${\textstyle k}$$ is the wavevector of the light ( See more • Mie scattering • Anomalous diffraction theory • Discrete dipole approximation See more Rayleigh–Gans approximation has been applied on the calculation of the optical cross sections of fractal aggregates.
