Experiment is using a 160 GeV beam of polarized muons and longitudinally polarized deuterium in a 6LiD double-cell target. The gluon polarization, {delta}g/g, is determined from the double-spin cross section asymmetries for the events selected by tagging the photon-gluon fusion process. We obtain three independent results at Xg{approx_equal}0.1.
