Does anybody know about a good calibration standard which can be used for peak shape control in the low angle region in neutron powder diffraction? Low angle meaning 2Theta = 5� - 20� with a wavelength of 1.6Ang -- a d-range of 20 Ang - 4.5 Ang. In this region the material should have a few a) strong and b) well resolved reflections.
