M064600100017 DETECTOR (SCIN) 5-cm diameter BC501A neutron detectors. M064600100018 SAMPLE Liquid scintillator (C-6)(D-12) 3.7 cm in diameter M064600100019 and 4.18 cm long. M064600100020 ERR-ANALYS (ERR-S) Statistical errors are presented. M064600100021 COMMENT The first measurement of the 2H(g-pol,n)p analyzing M064600100022 power near threshold has been performed using the M064600100023 High-Intensity Gamma-ray Source (HIGS) at the Duke M064600100024 Free-Electron Laser Laboratory. A 3.58 MeV g-ray M064600100025 beam having an energy resolution of 2.5 % and 100 % M064600100026 linear polarization was incident on an active M064600100027 liquid scintillating (C-6)(D-12) target. Outgoing M064600100028 neutrons were detected parallel and perpendicular to M064600100029 the plane of g-ray polarization at a lab angle of M064600100030 150 degree. The experimentally determined analyzing M064600100031 power provide a sensitive measurement of the the M064600100032 relative E1 and M1 contributions to the total cross M064600100033 section.
