Brockhouse, Bertram Neville (1918-2003), was a Canadian pioneer of neutron spectroscopy, a technique in which materials are bombarded with the subatomic particles called neutrons in order to determine a material's structure. He was awarded the 1994 Nobel Prize for physics, for the development of neutron spectroscopy, sharing it with Clifford Shull, who had developed the neutron diffraction technique (see Shull, Clifford Glenwood). Overall, the prize was awarded for pioneering contributions to the development of neutron-scattering techniques for studies of condensed matter.
