説明
<p>We developed the spin-contrast-variation neutron powder diffractometry to observe hydrogen atoms in a crystalline sample by polarized neutrons and by polarized protons in the crystal. With L-glutamic acid crystals dispersed in a deuterated polystyrene matrix containing a polarizing agent, we observed the intensities of the sample's diffraction peaks changing differently in accordance with the proton polarization. Diffraction peaks from hydrogen atoms can be extracted the spin-contrast-variation neutron powder diffractometry thanks to the variation of peak intensities as a function of proton polarization. This technique is expected to establish the method of analyzing structures of hydrogen-containing materials that are difficult to determine with conventional powder diffractometry.</p>
