Autores ResumoFrank Myers involved the construction of a Van de Graaf accelerator and the scattering of polarized electrons, so his focus was on nuclear physics.In June 1941, Cliff ®nished his thesis and accepted a job with the Texas Company (later to become Texaco) in Beacon, New York.With the Texas Company, Cliff's work was on the study and characterization of catalysts used in making high-octane aviation fuel.In this work, he used X-ray diffraction and small-angle-scattering techniques to study powder samples, which gave him valuable experience for his later work with neutrons.On a visit to Oak Ridge in April 1946, Cliff met Ernie Wollan and learned of Wollan's exploratory work on the diffraction of monochromatic neutrons by powder samples of NaCl and the scattering of neutrons by H 2 O and D 2 O. Cliff was immediately excited by this work and came to Oak Ridge in June 1946.Wollan had been a student of Arthur Compton at the University of Chicago and was well versed in the theory and practice of X-ray diffraction.When Shull arrived, Wollan had already assembled a two-axis neutron diffractometer, using a large NaCl crystal as monochromator and moving from Chicago the Comptondesigned sample table and counter arm that Wollan had used in his thesis work.
