C304500100015 DETECTOR (MAGSP,IOCH,SCIN) Super-Enge Split-Pole Spectrograph C304500100016 (SE-SPS), where its two dipole magnets focused the C304500100017 charged particles toward the focal-plane detector. C304500100018 The detector includes a position-sensitive ionization C304500100019 chamber filled with isobutane gas, and a plastic C304500100020 scintillator for measuring the remaining energy of C304500100021 the particles after passing through the ionization C304500100022 chamber. C304500100023 SAMPLE (5-B-11,ENR=0.99) The first was a self-supporting 10B C304500100024 target containing 11B, 12C, and 16O contaminants with C304500100025 a total density of about 70 microg/cm2. The 11B C304500100026 contamination was on the order of 8%. To assist in C304500100027 the identification of states coming from the 11B(d,p) C304500100028 12B reaction caused by the 11B target contamination, C304500100029 data were taken at each angle with a second target C304500100030 enriched in 11B (>99%) with a density of about C304500100031 70 microg/cm2 on a 20 microg/cm2 carbon backing. C304500100032 METHOD The targets were installed in the sliding-seal C304500100033 scattering chamber upstream of the SE-SPS. Particle C304500100034 trajectories can be reconstructed and momentum C304500100035 spectra can be constructed by using the acquired C304500100036 position information from position-sensitive anode C304500100037 pickup pads with delay-line readout. Particle C304500100038 (reaction) identification is achieved by measuring C304500100039 the energy loss in the ionization chamber and the C304500100040 remaining energy with the plastic scintillator. The C304500100041 solid-angle acceptance of the SE-SPS was set at 4.6 C304500100042 msr for this experiment. To determine differential C304500100043 cross sections at different scattering angles in the C304500100044 laboratory frame, measurements were performed from 10 C304500100045 to 50 in 5 degree steps. The magnetic field of the C304500100046 spectrometer was set to measure the 11B excitation C304500100047 energy range from about 8.4 to 13.6 MeV.

Because C304500200008 of the large number of counts for each peak, the C304500200009 statistical uncertainties are very small. Thus, when C304500200010 combined, the error bars tend to be right around 15% C304500200011 for each data point.
