This includes amongst others quantum computation and quantum communication. LÄS MER

  7. 5. Compton Scattering from the Deuteron at Low Energies

    Författare :Magnus Lundin; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Compton scattering; photonuclear reactions; deuteron; differential cross sections; 50-70 MeV; polarizability; tagged photons; Nuclear physics; Kärnfysik; Fysicumarkivet A:2002:Lundin;

    Sammanfattning : A series of three Compton scattering experiments on deuterium have been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 50 < Eg < 70 MeV tagged photons were scattered from a liquid deuterium target and detected simultaneously in three (10"x10") NaI detectors. LÄS MER
