F070700100010 INC-SPECT The beam energy spread, straggling in the target,and F070700100011 reaction kinematics limited the overall energy F070700100012 resolution to 350-650 keV depending on the scattering F070700100013 angle. F070700100014 DETECTOR (TELES,SIBAR)Reaction products were detected and F070700100015 identified with cooled dE-E telescopes consisting of F070700100016 four 2-mm Si surface-barrier counters. F070700100017 SAMPLE Natural oxygen gas was contained in a gas cell with F070700100018 2 mg/cm2 Havar windows at a pressure of about 200 Torr.F070700100019 MONITOR At extreme forward angles, where the gas target F070700100020 presented some difficulties,supplementary normalizationF070700100021 runs were performed with a 350 mu-g/cm2 Mylar target F070700100022 yielding an overall resolution of 220 keV.
