PDFgetN3: atomic pair distribution functions from neutron powder diffraction data using ad hoc corrections

This is the authors' abstract. We don't add key points for this paper.

PDFgetN3 , a new software tool for the extraction of pair distribution functions (PDFs) from neutron powder diffraction intensity data, is described. Its use is demonstrated with constant-wavelength neutron data measured at the new powder diffractometer PEARL at the Delft University of Technology. PDFgetN3 uses an ad hoc data collection protocol similar to PDFgetX3 . The quality of the resulting PDFs is assessed by structure refinement and by comparison with established results from synchrotron X-ray scattering.
