Abstract: The problem of the retrieval of the particle size distribution of scatterers from small-angle scattering experiments with noisy data is addressed. Gaussian-like particle size distributions of noninteractive spheres are used as illustrative examples. A numerical corrector method, previously reported by the present authors, is used for the retrieval process. The achievable information in real space is investigated with the help of numerical experiments, the solution of which is known in advance. Cases are solved assuming three different functional dependences of noise with scattering vector, which simulate experimental conditions. The method proves to be powerful in retrieving the correct information with noisy data. The reliability of the process is established as a function of noise level and particle size.
