Small-angle scattering data analysis for dense polydisperse systems: the FLAC program

Abstract FLAC is a program to calculate the small-angle neutron scattering intensity of highly packed polydisperse systems of neutral or charged hard spheres within the Percus–Yevick and the mean spherical approximation closures, respectively. The polydisperse system is defined by a size distribution function and the macro-particles have hard sphere radii which may differ from the size of their scattering cores. With FLAC, one can either simulate scattering intensities or fit experimental small angle ... Title of program: FLAC Catalogue Id: ADNF_v1_0 Nature of problem The problem is the calculation of the scattering cross section in small-angle scattering of polydisperse neutral and charged hard spheres. Both dense or dilute systems are considered.
