Which оf the fоllоwing three stаtements on the аdvаntage(s) of neutron diffraction over X-ray diffraction is/are true? (i) Neutron diffraction has improved sensitivity to low-Z elements such as C and H than X-ray diffraction. (ii) While both X-ray diffraction and neutron diffraction can be used to determine the lattice periodicity, neutron diffraction can provide additional information on the ordering of magnetic moments in a magnetic structure. (iii) Neutron diffraction has higher sensitivity to higher angle diffraction peaks than X-ray diffraction.
