The blast experiment

Polarized electron scattering from hydrogen and deuterium

Research output: Contribution to journalArticle

Abstract

At the MIT-Bates Linear Accelerator Center, the nucleon form factors have been measured by scattering polarized electrons from vector-polarized hydrogen and deuterium. The experiment used the longitudinally polarized electron beam stored in the MIT-Bates South Hall Ring along with an isotopically pure, highly vector-polarized internal atomic hydrogen and deuterium target provided by an atomic beam source. The measurements were carried out with the symmetric Bates Large Acceptance Spectrometer Toroid (BLAST). Results are presented for the proton form factor ratio, μp GE p/G M p, and for the charge form factor of the neutron, G E n. Both results are more precise than previous data in the corresponding Q2 ranges.
