C182800100014 SAMPLE Two (CH2)n targets were used during the experiment withC182800100015 thicknesses of 32+-2 and 34+-2 mu-g/cm2, respectively. C182800100016 The hydrogen content of the target was monitored by C182800100017 measuring the ratio of hydrogen to carbon recoils C182800100018 scattered, at a given angle, by the beam. When the C182800100019 ratio dropped significantly, the target was replaced. C182800100020 INC-SOURCE High-intensity 18F4+ beam with average 5 x 10E+6 pps C182800100021 from ISAC was used.The 18-O contamination in the beam C182800100022 was monitored throughout the experiment and dropped C182800100023 from an initial 70% (during 673 keV runs) to less C182800100024 than 5% during the 250 keV data runs. C182800100025 DETECTOR (SISD) Coincident alpha-particle and heavy-ion C182800100026 products were detected by highly segmented silicon C182800100027 strip detector arrays, providing particle energy, C182800100028 time-of-flight, and scattering angle information. One C182800100029 silicon strip detector array (LEDA-2) was positioned C182800100030 upstream covering laboratory angles from 120 to 146 C182800100031 deg. Three further silicon strip detector arrays C182800100032 (LEDA-1,S2-1,S2-2) covered downstream laboratory C182800100033 angles from 4 to 69deg.
