Warren-Averbach line broadening analysis from a time of flight neutron diffractometer
David M. Collins, Angus J. Wilkinson, Richard I. Todd
The well known Warren-Averbach theory of diffraction line profile broadening is shown to be applicable to time of flight data obtained from a neutron spallation source. Without mod…
