21. Ancient and historic steel in Japan, India and Europe, a non-invasive comparative study using thermal neutron diffraction . 22. This leads to a very high background in neutron diffraction experiments, and may make structural investigations impossible. 23. X-ray or neutron diffraction are therefore often the preferred methods for determining lattice parameters and atomic positions. 24. The beamline uses neutron diffraction to determine the spacing between layers of atoms in order to measure elastic strength. 25. Small-angle X-ray scattering ( X-ray and neutron diffraction , wide angle X-ray scattering, as well as to static light scattering. 26. The structures of metal hydride complexes, e . g ., Mg 2 FeH 6 have been assessed by neutron diffraction . 27. Neutron diffraction confirmed that LFP was able to ensure the security of large input / output current of lithium battery.28. Crystal growth, structure determination by X-ray and neutron diffraction , and thermal analysis are also important aspects of Dr . Haile's research. 29. Neutron diffraction techniques may therefore be used to detect light elements such as oxygen or hydrogen in combination with heavy atoms.30. Below 118 K MnO is antiferromagnetic . to have its magnetic structure determined by neutron diffraction , the report appearing in 1951.
