C008800100008 FACILITY (DYNAM,1USAANL) C008800100009 SAMPLE 260 microg/cm2 U3O8. C008800100010 DETECTOR (COIN,PGAC,PGAC) Parallel-grid avalanche counters C008800100011 (SOLST) Surface barrier detector at 165 degrees to C008800100012 monitor the beam. C008800100013 METHOD (COINC) PGAC's placed at 90 degrees to beam direction C008800100014 in kinematic coincidence. Solid angle 1.8 str. C008800100015 (20x20 cm2). C008800100016 Beam current (300 - 900 na.) measured by Faraday Cup. C008800100017 Irradiation time was 2 hours at 4.45 MeV and 14 hours C008800100018 at 3 MeV. C008800100019 ANALYSIS Assumed isotrpic angular distribution of fission C008800100020 fragments. C008800100021 ERR-ANALYS (DATA-ERR) Total uncertainty includes statistical C008800100022 uncertainty in number of fissions observed and C008800100023 estimated 3% uncertainty in solid angle of detectors. C008800100024 STATUS (TABLE) Data taken from Table 1 of reference. C008800100025 Value given at 4.0 MeV in table has been corrected. C008800100026 (APRVD) Approved by B. Back, 25 Nov 1998.
