Measurements of the deuteron elastic structure function A(Q2) at the Jefferson Laboratory

Results from experiment E91-026 in Hall A at the Jefferson Laboratory are reported. The aim of this experiment was to extract the deuteron structure function A(Q2) from the coincidence elastic electron-deuteron cross-section measurements. A squared four-momentum transfer (Q2) range of 0.7 to 6.0 (Gev/c)2 was covered. Data from this experiment improve the quality of existing data at the low end as well as significantly extend the Q2 range. The results are compared to conventional meson-nucleon calculations based on both the non-relativistic and relativistic impulse approximation. They are also compared to predictions of dimensional scaling and perturbative quantum chromodynamics
