SAXSFit: A program for fitting small-angle x-ray and neutron scattering data

Abstract

SAXSFit is a computer analysis program that has been developed to assist in the fitting of small-angle x-ray and neutron scattering spectra primarily from nanoparticles (nanopores). The fitting procedure yields the pore or particle size distribution and eta parameter for one or two size distributions (which can be log-normal, Schulz, or Gaussian). A power-law and/or constant background can also be included. The program is written in Java so as to be stand-alone and platform-independent, and is designed to be easy for novices to use, with a user-friendly graphical interface.
