First measurement of the near-threshold 2 H(γ ,n)p analyzing power using a free-electron laser based γ-ray source

Journal Article (Journal Article)

The first measurement of the 2H(γ→,n)p analyzing power near threshold has been performed using the High-Intensity Gamma-ray Source (HIGS) at the Duke Free-Electron Laser Laboratory. A 3.58 MeV γ-ray beam having an energy resolution of 2.5% and 100% linear polarization was incident on an active C6D12 target. Outgoing neutrons were detected parallel and perpendicular to the plane of γ-ray polarization at a lab angle of 150°. The experimentally determined analyzing power provides a sensitive measurement of the relative E1 and M1 contributions to the total cross section.
