[deuter(ium) + –on.]


  • Speaking of which I know that the binding energy of a deuteron is about 2.2 MeV.

    Friday! August 07 – The Bleat.

  • QED, such as a precise measurement of the Lamb shift of the 1S ground state, and accurate determinations of the rms charge radius of the proton and the structure radius of the deuteron.

    Theodor W. Hänsch - Autobiography

  • In 1938 the first European cyclotron at Collège de France in Paris accelerated a deuteron beam up to 4 MeV and by hitting a target, an intense source of neutrons was produced.

  • I should try to develop a Green's function variational method for three-body scattering problems, like low-energy neutron-deuteron scattering, while warning me ominously, that he himself had tried and failed.

    Walter Kohn - Autobiography

  • Originally I had planned to revert to nuclear physics there, in particular the structure of the deuteron.

    Walter Kohn - Autobiography

  • The last measurement we did at the CEA was a measurement of the deuteron form factor at the highest momentum transfers that could be reached at that accelerator to get some limits on the size of relativistic effects and meson currents.

    Jerome I. Friedman - Autobiography

  • In an experiment to measure a weighted sum-rule for inelastic electron deuteron scattering which was related to the n-p interaction I had to confront the problem of making radiative corrections to inelastic spectra, and I developed a technique which proved to be valuable in my later work.

  • Zacharias, Kellogg, Millman and Kusch, in the new field of magnetic resonance and to share in the discovery of the deuteron quadrupole moment.

    Norman F. Ramsey - Autobiography

  • Besides we performed some scattering experiments and studied first the electric disintegration of the deuteron, and not to forget for the first time we measured the Lamb shift in the

    Wolfgang Paul - Autobiography

  • My job was to make the relatively short-lived mercury-197 isotope by using the MIT cyclotron to bombard gold with a deuteron beam, a kind of reverse alchemy.
