Deuteron Spin Observables from Electron Scattering at IntermediateEnergies

摘要

Double-polarization asymmetries have been measured for the (e,e'p) electrodisintegration from vector polarized deuterium over a range of four-momentum squared, Q2 from 0 1 to 0.7 (GeV/c)2, and a missing momentum range from 0 to 475 (MeV/c). Simultaneously, single polarization asymmetries have been measured from tensor polarized both in the elastic channel as well as in the (e, e'p) reaction channel. These sets of polarization observables have been obtained with great statistical precision and low systematical errors. They are compared with theoretical calculations and provide a new way to test the ground state wave function and the electromagnetic currents that connect to the continuum np system.
