O060300100013 METHOD (FISCT) O060300100014 DETECTOR (TRD) Makrofol polycarbonate detectors consisted of O060300100015 two sheets of a size of 3*4*0.02 cm forming a O060300100016 sandwich. Detector was sensitive to fragments with O060300100017 A>=16. Heavy reaction fragments were stopped inside O060300100018 the Makrofol sheets and could thus be detected in a O060300100019 4Pi geometry. O060300100020 CORRECTION Performed: Loss of events of about 2% due to removal O060300100021 of the detector material in the course of chemical O060300100022 treatment. O060300100023 Negligible: Casual coincidences between two individualO060300100024 tracks and an individual track with binary events. O060300100025 COMMENT - By Authors- Binary fission induced by high-energy O060300100026 particles is defined as a decay of nucleus into two O060300100027 fragments of approximately equal masses with an angle O060300100028 between their emission directions larger than 90 degr. O060300100029 Events with three tracks are defined as ternary fissionO060300100030 regardless of the mechanism of their production. O060300100031 HISTORY (19971206C) AP: By Khlopin's Institute.
