Differences have been found in the outer part of the neutron and x-ray small-angle scattering curves for various porous shaly rocks, and are analyzed in terms of fractal interfaces. Neutrons are relatively insensitive to the presence of either hydrocarbons or water in the pores, and always give a smaller Porod exponent than that for x rays, indicating that the hydrocarbon and/or water tend to reside in the small re-entrant parts of the mineral-pore interfaces

    In the context of one-dimensional linear wave propagation, a gradient-type interface is a point at which the velocity profile of a scattering medium suffers a jump in first derivative. In this paper, a time domain approach to scattering from such an interface leads to an integrodifferential...
