ON SOME ASPECTS OF AN HG BASED EPR EXPERIMENT

An experimental realization of Bohm's spin-1/2 EPR gedanken-experiment is possible using the spin-1/2 nuclei of the isotope Hg-199. The diss ociation of dimers of the Hg-199(2) isotopomer, using a spectroscopica lly selective stimulated Raman process, leads to the generation of an entangled state between the two Hg-199 atoms. The measurement of nucle ar spin correlations between the two atoms in this entangled state is achieved by detection of the atoms using a spin state selective two ph oton excitation-ionization scheme. The experiment will not only close the detector efficiency loophole, but in addition will permit enforcem ent of the locality condition. Effects of imperfect analyzers will als o be discussed.
