Scattering of Neutrons by Spin Waves in Magnetite in Physical Review, Volume 106, No. 5, June 1, 1957, pp. 859-865
Lancaster: American Institute of Physics, 1957. 1st Edition. FIRST EDITION IN ORIGINAL WRAPS OF A NOBEL PRIZE WINNING PAPER DEMONSTRATING THE FIRST USE OF INELASTIC NEUTRON SCATTERING TO STUDY SPIN WAVE DISPERSION RELATIONS” (Callaway, Quantum Theory of the Solid State, 321). Brockhouse’s technique enabled the study of excitations in solids and his work remains of practical and theoretical import and is now available for use in many differing types of systems.
Bertram Brockhouse, a Canadian physicist, shared the 1994 Nobel Prize in Physics with American physicist Clifford Shull "for pioneering contributions to the development of neutron scattering techniques for studies of condensed matter" (Nobel Prize Committee). The Committee went on to not that Brockhouse’s half of the prize was “for the development of neutron spectroscopy” and Shull’s half was “for the development of the neutron diffraction technique” (ibid).
“Atomic nuclei are composed of protons and neutrons. Brockhouse and Shull developed methods for investigating different materials with beams of neutrons created in a nuclear reactor. When neutron beams come in contact with a material, some of the neutron's energy is converted into vibrations. The vibrations, known as phonons, correspond to fixed energy levels that form a spectrum. During the 1950s Bertram Brockhouse developed methods for using these spectrums to chart properties of different molecules and materials” (ibid).
Specifically, Brockhouse developed “Triple-axis spectrometers (TASs) [as] classic steady-source instruments for inelastic scattering studies” (Carpenter, Elements of Slow-Neutron, 225). The triple-axis spectrometer is so named because there are three rotation axes: “those of the monochromator, the sample, and the analyzer” (ibid). Brockhouse’s methodology remains “the most informative and direct method used to study the laws of magnon dispersion and to observe other magnetic excitations involving the inelastic scattering of neutrons” (Spin Waves and Magnetic Excitations, xv).
