3 Dynamics of Very Light Nuclei 3 . 1 Polarized - Beam and Polarized - Target Reactions 3 . 1 . 1 A Polarized Solid 3 He Target for Neutron - Transmission Experi - ments
In the past year we have completed measurements of polarized neutron–polarized He scattering in the few MeV region. Measurements of the total cross-section differences ∆σT and ∆σL have been obtained for neutrons with incident energies 1-10 MeV. The results are sensitive to the excited state structure of the alpha particle and may be compared to phase-shift predictions based on a number of analy...
متن کاملImaging of laser-polarized solid xenon.
The enhanced spin polarization produced by optical pumping of gaseous rubidium/xenon samples has made possible a number of recent experiments in nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI). Here we report MRI of laser-polarized xenon in the solid phase at low temperature. Due to the high xenon density in the solid phase and the enhanced spin polarization, ...
متن کاملModeling Alignment Enhancement for Solid Polarized Targets
A model of dynamic orientation using optimized radiofrequency (RF) irradiation produced perpendicular to the holding field is developed for the spin-1 system required for tensor-polarized fixed-target experiments. The derivation applies to RF produced close to the Larmor frequency of the nucleus and requires the electron spin-resonance linewidth to be much smaller than the nuclear magnetic reso...
متن کاملA Study of Final State Effects in the Electrodisintegration of a Polarized Helium-3 Target
An approach for the description of the final state interaction in the evaluation of inclusive electromagnetic responses of a polarized He target, is briefly illustrated. Preliminary results of calculations, where the final state interaction is fully taken into account for the two-body break-up channel, are compared with experimental data, showing a very encouraging improvement with respect to t...
متن کاملSeaQuest with a Transversely Polarized Target (E1039)
We have constructed a state-of-the-art, high luminosity polarized proton and deuteron target and propose to measure the Sivers asymmetry for the ū and d̄ sea quarks in the nucleon for four different Bjorken xB bins in the range 0.1 < xB < 0.5, using the Drell-Yan process at SeaQuest. We will: i) perform the first measurement of the Sivers asymmetry in Drell-Yan scattering for sea quarks; ii) det...
