T004700100011 METHOD (COINC,PSD) Pair coincidence spectrometry and pulse T004700100012 shape-discrimination were used T004700100013 DETECTOR (NAICR) A 7.6-cm x 7.6-cm cylindrical 'plug' detector T004700100014 surrounded by an axially split NaI(Tl) annulus in T004700100015 anticoincidence mode used to detect gammas. T004700100016 (SIBAR) The detector consisted of a 1-mm-thick silicon T004700100017 detector which was fixed at an angle 135. degr. T004700100018 relative to the forward beam direction and was T004700100019 protected from the back-angle elastically deuterons T004700100020 by a 2-mg/cm2 aluminum foil. T004700100021 MONITOR Detection efficiency measured using 11B(p,gamma) and T004700100022 11B(p,alpha) reactions at 163 keV. T004700100023 ERR-ANALYS (ERR-SYS) Systematic uncertainty of about 20% T004700100024 primarily due to the reported error in the branching T004700100025 ratio of the 11B(p,gamma)/11B(p,alpha) reactions T004700100026 which was used to determine the efficiency in the T004700100027 present measurement.
