Electron scattering from polarized deuterium at VEPP-3
- and others
The experiment to measure the tensor analyzing power T{sub 20} of the deuteron using a tensor-polarized internal target at the VEPP-3 electron storage ring in Novosibirsk is currently in its second phase. Tensor-polarized deuterium atoms from an atomic beam source feed an active storage cell in the electron ring, serving as the target for a beam of 2 GeV unpolarized electrons. Analysis of the first Phase 2 data in the kinematic range Q{sup 2} = 0.36 {minus} 0.50 (GeV/c){sup 2} is reported here. Plans for the third phase of the experiment, which will use a high-density, laser-driven polarized deuterium target, are also discussed. The measurement of T{sub 20} from the second and third phases of the experiment will cover the kinematic region 0.36 {le} q {le} 0.90 (GeV/c){sup 2} where T{sub 20} is particularly sensitive to isoscalar meson exchange currents.
