Canadian physicist Bertram Neville Brockhouse, who received the Nobel Prize in physics in 1994, died Monday. He was 85. An emeritus professor of physics at McMaster University in Hamilton, Ontario, Brockhouse shared the Nobel with American physicist Clifford G. Shull for their separate but concurrent development of neutron-scattering techniques. He conducted his award-winning work from 1950 to 1962 at the Chalk River Nuclear Laboratory, operated by Atomic Energy of Canada. Brockhouse used inelastic neutron scattering in his pioneering examination of phonons, which are units of the lattice vibrational energy expended by the scattered neutrons. He also developed the neutron spectrometer and was one of the first to measure the phonon dispersion curve of a solid. . . . Bookham Technology has bought a Palomar Technologies laser diode assembly cell to manufacture its chip-on-carrier tunable laser devices at its facility in South Devon, England. The high-precision assembly system automates laser diode component assembly. . . . Eastman Kodak said it will expand the availability of its radiology information system, now used in Europe and Australia, to medical facilities in the US in 2004.
