Title Dynamical Diffraction Peak Splitting in Time-of-Flight Neutron Diffraction
Abstract Time-of-flight neutron diffraction data from 20 mm and 0.7 mm thick perfect Si single crystal samples, which exhibit dynamical diffraction effects associated with finite crystal size, are presented. This effect is caused by constructive interference occurring solely from thin layers bounded by the front (entry) and back (exit) surfaces of the sample with no scattering originating from the layers in between, resulting in two distinct peaks observed for each reflection. If the sample is thin and/or the instrument resolution is insufficient, these two peaks can convolve and cause peak shape aberrations which can lead to significant errors in strain and peak-broadening parameters obtained from a kinematical diffraction analysis.
