with 𝜌 > % (𝑟) being the convolution square of the spatially averaged excess electron density ρ(r), relative to the buffer. In the case of spherical geometry, deconvolution of the p(r) gives the radial contrast profile in electron density ρ(r) relative to the mean value of the solvent. This gives information about the internal structure of the scattering particles. The fitting parameter can be found in Table .
