Inelasticity correction for liquid and amorphous samples containing large amount of hydrogen atoms

The present status of the inelasticity correction for liquid and amorphous samples is provided. Although numerous theoretical approaches have been reported, inelasticity correction which can generally be applied to any sample containing large amount of hydrogen atoms has not yet been proposed. We introduce some experimental methods to estimate inelasticity correction curve which can effectively be applied for time-of-flight neutron diffraction experiments. (author)
