X-rays are scattered by atomic electrons, neutrons by atomic nuclei. The two techniques are not in competition; they are complementary. Because neutron sources are many orders of magnitude weaker than X-ray sources, it is likely that neutron scattering will not be used for routine structure determination but will be important for the determination of the position of the crucial hydrogen atoms. The following discussion is brief; details can be found in a number of books, reviews, and papers –.
