The indirect Fourier transform method for obtaining distance distribution functions and associated parameters from small‐angle X‐ray scattering data was adapted for studies of particles having radii of gyration up to 35000 Å and distance distribution functions extending up to 150 000 Å. Data were collected with a Bonse–Hart instrument. Distance distribution functions were obtained for materials of interest to petroleum production, including a powdered wax, a powdered asphaltene, a crude oil, and emulsions of dilute aqueous solutions of a partially hydrolyzed polyacrylamide polymer shaken with organic solvents.
