Spin-momentum correlations in quasielastic electron scattering from deuterium.
نویسندگان
چکیده
The spin-momentum correlation parameter A(V)(ed) was measured for the 2H-->(e-->,e'p)n reaction for missing momenta up to 350 MeV/c at Q2 = 0.21 (GeV/c)(2) for quasielastic scattering of polarized electrons from vector-polarized deuterium. The data give detailed information about the deuteron spin structure and are in good agreement with the results of microscopic calculations based on realistic nucleon-nucleon potentials and including various spin-dependent reaction mechanism effects. The experiment reveals in a most direct manner the effects of the D state in the deuteron ground-state wave function and shows the importance of isobar configurations for this reaction.

QUEEG: A Monte Carlo Event Generator for Quasielastic Scattering on Deuterium
We have developed a simulation of quasielastic electron scattering off nucleons in deuterium. The original code was developed by J.Lachniet for the analysis of the CLAS6 GM experiment. The Fermi motion of the nucleons creates an effective beam energy different from the laboratory one as seen from the rest frame of the moving nucleon. This effective beam energy is used with the Hulthen distribut...
متن کاملRelativistic and nuclear structure effects in parity-violating quasielastic electron scattering.
The parity violating longitudinal asymmetry A is calculated for quasielastic electron scattering. We use a variety of relativistic mean field models for the response of nuclear matter and 12 C at a momentum transfer of q=550 MeV/c. Relativistic effects from a reduced nucleon mass, RPA correlations and vacuum polarization can all change A by a relatively large amount. These large nuclear structu...

We have measured the beam-normal single-spin asymmetries in elastic scattering of transversely polarized electrons from the proton, and performed the first measurement in quasielastic scattering on the deuteron, at backward angles (lab scattering angle of 108°) for Q² = 0.22 GeV²/c² and 0.63 GeV²/c² at beam energies of 362 and 687 MeV, respectively. The asymmetry arises due to the imaginary par...
متن کاملRelativistic models for quasielastic (e,e') at large momentum transfers.
Inclusive quasielastic response functions are calculated for electron scattering in a relativistic model including momentum dependent scalar and vector mean fields. The momentum dependence of the mean fields is taken from Dirac optical fits to proton nucleus scattering and is important in describing data at momentum transfers of 1 GeV/c or larger. Our simple model is applicable for quasielastic...
متن کاملQuasielastic Nucleon Scattering Using Polarized Beams and Targets
Inelastic scattering of polarized intermediate energy nucleons to continuum nuclear states is discussed with emphasis on recent results. Spin momentum correlations of protons i n polarized targets of 3He were observed for the first time. Complete spin observables in (g$) show effects of the nuclear spin-isospin response and of an NN interaction modified by the nuclear medium. A comparison of Ga...
