Here is the Abstract that for the poster that Dustin will be giving at the March APS meeting A proton polarimeter is being designed to measure relevant polarization transfer coefficients of the ³He(d,p)⁴He reaction at very low energies, near the 430 keV resonance. The ³He(d,p)⁴He experiment will be carried out at the Low Energy Beam Facility at Triangle Universities Nuclear Lab, in collaboration with researchers from the University of North Carolina-Chapel Hill. Research has been done on the feasibility of using ⁴He-p elastic scattering in conjunction with a vane type gas cell polarimeter for polarization measurements. Mathematical fits were made to existing ⁴He(p,p)⁴He differential cross section and analyzing power data, as well as ³He(d,p)⁴He total cross section data. These fits have been used in conjunction with a Monte Carlo solid angle calculation for a vane type polarimeter to determine the optimum vane angle for the polarimeter under these experimental conditions.
