      abstract     = {A dilute dispersion of charge-stabilized, monodisperse
                      silica nanoparticles has been used to determine the
                      instrumental resolution function parameters of a
                      conventional small-angle neutron scattering instrument in
                      pinhole geometry over the entire accessible range of
                      momentum transfer q. Independent determination of the
                      structure parameters of the colloidal silica dispersion by
                      small-angle X-ray scattering enables refinement of both the
                      q-independent geometric and the q-dependent ( wavelength
                      spread or polychromaticity of the neutron beam)
                      contributions to the resolution function. The procedure
                      described is appropriate if no further instrumental
                      characterization is available. It is demonstrated that the
                      sample used for refining the resolution function parameters
                      has to exhibit sharp structural scattering features such as
                      Bragg reflections, form factor maxima and minima, or an
                      inter-particle correlation peak for each instrumental
                      configuration at which the measurements have been performed
                      to cover a q range of two orders of magnitude (0.03 < q <
