Preliminary Results of 2H (e, e'p) n in Blast

Due to its simple composition, the deuteron has long been recognized as important in understanding the structure of the inter-nucleon potential. With this goal, a comprehensive study of low- {Q}² spin-dependent electron scattering from deuterium is currently underway using the polarized electron beam provided by the MIT-Bates linear accelerator. Using the BLAST (Bates Large Acceptance Spectrometer Toroid) detector together with an internal vector/tensor polarized deuterium target, a comprehensive spin-dependent analysis of proton scattering is being performed. Due to the detector's large acceptance and symmetric design, simultaneous determination of the deuteron's parallel and perpendicular asymmetries is possible over a {Q}² range between 0.1 and 0.5 GeV². Preliminary asymmetry results are presented here along with a comparison with theory.
