Measurement Of Quasi-Elastic He-3((P)Over-Right-Arrow,Pn) Scattering From Polarized He-3 And The 3-Body Ground-State Spin Structure

We report measurements of spin correlations and analyzing powers in He3(p, 2p) and He3(p, pn) quasielastic scattering as a function of momentum transfer and missing momentum at 197 MeV using a polarized internal target at the Indiana University Cyclotron Facility Cooler Ring. At sufficiently high momentum transfer we find He3(p, pn) spin observables are in good agreement with free p-n scattering observables, and therefore that He3 can serve as a good polarized neutron target. The extracted polarizations of nucleons in He3 at low missing momentum are consistent with Faddeev calculations. © 1995 The American Physical Society

Spin-Dependent Scattering Of Polarized Protons From A Polarized He-3 Internal Gas-Target

We describe the first experiment to use a polarized internal gas target and polarized beam in a storage ring. A laser optically pumped polarized He internal gas target has been used with circulating beams of 197-414 MeV polarized protons to carry out an extensive set of measurements of spin dependent scattering. A large acceptance non-magnetic detector system consisting of wie-chambers, scintillators and microstrip detectors was used to detect protons, neutrons, deuterons, and He-3 nuclei from the beam-target interaction. It is demonstrated that these techniques result in low backgrounds (< 1%) due to scattering from species other than the polarized target gas and allow detection of low energy recoiling nuclei. Specific issues such as interfacing the experiment to the storage ring and monitoring the luminosity and polarizations are discussed in detail
