C241800100013 SAMPLE The 250Cf target had a thickness of ~50 microg/cm2 on C241800100014 a 60 microg C backing. C241800100015 PART-DET (P,FF) C241800100016 DETECTOR (TELES) The telescope consisted of dE and E C241800100017 semiconductor detectors. C241800100018 METHOD (EDE,COINC) Coincident fission fragments were counted C241800100019 in two pairs of heavy ion semiconductor detectors C241800100020 placed at approximately 0 and 90 degrees with respect C241800100021 to recoil axis of the 252Cf nucleus. Systematic C241800100022 errors due to radiation damage or gain fluctuations C241800100023 of the surface barrier detectors were kept to a C241800100024 minimum.
