Sažetak
The scattering curves for various models of spherical particles of non-uniform electron density were calculated and compared with scattering curves for homogeneous particles. Simple asymptotic laws were found for average intensities which show h-n dependence, where h is proportional to the scattering angle. Whenever the electron density transition is sharp, or partly gradual and partly sharp, the exponent n is 4 regardless whether the sharp transition is at the edge of or inside the particle. If the whole electron density transition is gradual, n is greater than 4; n = 6 if the transition is linear, and n = 8 if the transition can be described by a cosine function.
