Two low F081800100018 pressure multiwire proportional chambers located 1.5 F081800100019 and 0.3 m upstream from the target were used to detect F081800100020 the incident nuclei. F081800100021 DETECTOR (SISD,SILI,CSICR)The energy and angle of the recoiling F081800100022 protons were measured using four silicon-strip F081800100023 detectors, placed at 20 cm from the target, backed by F081800100024 Si(Li) diodes and CsI crystals read out by photodiodes.F081800100025 The doubled-sided silicon strip detectors were 6*6 cm2 F081800100026 in size, 300 mu-m thick with 60 strips 1 mm wide on F081800100027 each side providing for localization in X and Y. F081800100028 The energy resolution for protons in the silicon strip F081800100029 detectors was 70 keV, and the angular resolution 0.29 F081800100030 degr. F081800100031 (TELES)The telescopes were placed at two settings F081800100032 covering laboratory angles between 56 and 86 degr. F081800100033 for the 20O measurements. In the case of 18O, due F081800100034 to limited beam time, only one setting was used F081800100035 covering a range between 56 and 72 degr. F081800100036 METHOD (TOF) F081800100037 (EDE) F081800100038 SAMPLE 2.3 mg/cm2 polypropylene (C2H)n target located at the F081800100039 center of the scattering chamber was used. F081800100040 COMMENT The absolute normalization was deduced from the number F081800100041 of incident nuclei and the target thickness. The error F081800100042 on the normalization is estimated to be 10% including F081800100043 the background effect.
