C265900100012 SAMPLE Targets were produced under vacuum by thermally C265900100013 evaporating NaBr powder onto 22 mu-g/cm2-thick C265900100014 natural carbon backing foils. The NaBr thickness, as C265900100015 measured with a thickness monitor during evaporation, C265900100016 was approximately 70 mu-g/cm2. The exact sodium C265900100017 concentration was not required for the experiment C265900100018 since the measurement was performed relative to the C265900100019 elastic scattering cross section. C265900100020 METHOD (EDE) The proton transfer experiment was performed at C265900100021 TUNL using the Enge split-pole spectrograph. The C265900100022 instrument is located at the end of the C265900100023 high-resolution beam line at the TUNL Tandem C265900100024 accelerator laboratory, where two 90-degree dipole C265900100025 analyzing magnets deliver beams of precisely C265900100026 controlled energies to the target. A 3He++ beam C265900100027 energy of 21 MeV was chosen to minimize the presence C265900100028 of contaminants in spectral areas. The NaBr targets C265900100029 were placed on a target ladder along with a natural C265900100030 carbon backing foil for background identification. C265900100031 The beam current was monitored with an C265900100032 electron-suppressed beam stop downstream from the C265900100033 targets. A silicon telescope was placed at 45 degree C265900100034 to monitor target degradation, and beam fluctuations, C265900100035 and to normalize the data. Reaction products from the C265900100036 target entered the Enge split-pole spectrograph C265900100037 through a 1 msr aperture and were momentum-analyzed C265900100038 with a magnetic field. Deuterons were clearly C265900100039 identified with a dE vs E cut. These spectra were C265900100040 internally calibrated using precisely known states in C265900100041 24Mg. C265900100042 ANALYSIS Over the entire focal plane, most states are in good C265900100043 agreement with the literature energies with an average C265900100044 deviation of 1.3-sigma.
