  We report on a measurement of the tensor-analyzing power T20 in elastic
electron-deuteron scattering in the range of four-momentum transfer from 1.8 to
3.2 fm-1. Electrons of 704 MeV were scattered from a polarized deuterium
internal target. The tensor polarization of the deuterium nuclei was determined
with an ion-extraction system, allowing an absolute measurement of T20. The
data are described well by a non-relativistic calculation that includes the
effects of meson-exchange currents.
