On Some Aspects of an Hg Based EPR Experiment Academic Article uri icon


  • An experimental realization of Bohm's spin-1/2 EPR gedanken-experiment is possible using the spin-1/2 nuclei of the isotope 199Hg. The dissociation of dimers of the 199Hg2 isotopomer, using a spectroscopically selective stimulated Raman process, leads to the generation of an entangled state between the two 199Hg atoms. The measurement of nuclear spin correlations between the two atoms in this entangled state is achieved by detection of the atoms using a spin state selective two photon excitation-ionization scheme. The experiment will not only close the detector efficiency loophole, but in addition will permit enforcement of the locality condition. Effects of imperfect analyzers will also be discussed.
