C156700100012 INSTITUTE (1USAORL,1USATEN,1USACSM,1USATTU,1USANCA,1USARUT) C156700100013 FACILITY (VDGT,1USAORL) The Holifield radioactive ion beam C156700100014 facility (HRIBF) at Oak Ridge national laboratory. C156700100015 INC-SPECT Low-energy beams of 17O from the HRIBF tandem C156700100016 accelerator with an intensity of about 1 pna. C156700100017 SAMPLE Windowless gas target. Large scattering chamber C156700100018 filled with hydrogen gas at a pressure of 4 torr. C156700100019 Ultrahigh purity gas (>99.999% H2). C156700100020 DETECTOR (SIBAR) Nitrogen recoils from the 1H(17O,alpha)14N C156700100021 reaction have laboratory angles <21 degree and thus C156700100022 pass through the center of the annular Silicon C156700100023 Detector Array (SIDAR) from any point of origin inside C156700100024 the target chamber. C156700100025 METHOD (COINC) The alpha and 14N reaction products were C156700100026 detected in coincidence by an array of silicon strip C156700100027 detectors operating within the hydrogen gas C156700100028 environment. The kinematics and relative timing of C156700100029 the two detected particles allowed the 1H(17O,alpha) C156700100030 14N reaction to be cleanly distinguished.

C156700300005 ERR-ANALYS (ERR-T) The three largest sources of purely systematic C156700300006 uncertainties in the resonance strength were: C156700300007 the thickness of the carbon foil used for beam current C156700300008 normalization (6% arising primarily from the C156700300009 uncertainty in stopping powers for alpha particles in C156700300010 carbon), the strength of the alpha source used for C156700300011 efficiency calibrations (3%), and the stopping power C156700300012 for 17O in hydrogen gas (2% as determined in this C156700300013 measurement). Adding each of these uncertainties in C156700300014 quadrature with the result from the fit to the yield C156700300015 curve produces a final result. C156700300016 (ERR-1) Carbon foil thickness. C156700300017 (ERR-2) Alpha source strength. C156700300018 (ERR-3) Stopping power of 17O.
