The first measurement of the {sup 2}H({gamma}(vector sign),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 {gamma}-ray beam having an energy resolution of 2.5% and 100% linear polarization was incident on an active C{sub 6}D{sub 12} target. Outgoing neutrons were detected parallel and perpendicular to the plane of {gamma}-ray polarization at a lab angle of 150 degree sign . The experimentally determined analyzing power provides a sensitive measurement of the relative E1 and M1 contributions to the total cross section. (c) 2000 The American Physical Society.
