给出了中子波长为1.063埃的气体氮、四氟化碳和甲烷的中子衍射图。结果表明，氮和氟的相干散射截面几乎等于总散射截面，四氟化碳中C-F键长为1.33讨论了微分散射截面半经典形式的误差。
Neutron diffraction patterns for the gases nitrogen, carbon tetrafluoride, and methane are given for a neutron wavelength of 1.063 A. It is found that the coherent scattering cross sections of nitrogen and fluorine are nearly equal to the total cross sections, and that the C—F bond length in carbon tetrafluoride is 1.33 A. The error in a semiclassical form of the differential scattering cross section is discussed.
