Illuminating the Deuteron at Jefferson Lab
Physics Division Colloquium - 8 Sept 2000

During the past decade, the quest to observe effects of quantum chromodynamics (QCD) in a nuclear reaction has been one of the central goals of nuclear physics. Since the beginning of the physics program at Jefferson Lab in 1994, a substantial amount of effort has been devoted to the study of the most basic nucleus, the deuteron, in an attempt to observe QCD effects. Recent findings from these experiments will be reviewed. Although Jefferson Lab was originally designed as a 4 GeV electron scattering facility, recent results up to 5.5 GeV will be presented. There is mounting evidence that the traditional Yukawan (nucleon-meson) picture of nuclei breaks down in high energy photoreactions as quark effects become apparent.
