This technique’s inputs are guided using “supermirrors” consisting of glass tubes coated with titanium and nickel. Whether this technique uses a coherent source determines whether the Debye–Waller or Lamb–Mössbauer factor is used. A class of instruments (-5[1])for this technique explore phase space by rotating a crystal monochromator, the sample, and a crystal called the analyzer. The (-5[1])first direct evidence of antiferromagnetic (15[1])ordering in (*) molybdenum oxide was observed using this technique, whose development led to a Nobel in Physics for Clifford Shull and Bertram (10[1])Brockhouse. (10[1])At Oak Ridge National Laboratory, (10[1])this technique uses either the High Flux Isotope Reactor or a spallation source. For 10 points, (10[1])name this technique that probes material structure by measuring the deflection of namesake uncharged particles. ■END■ (10[6]0[2])
