O0603 1 13 METHOD (FISCT) O0603 1 14 DETECTOR (TRD) Makrofol polycarbonate detectors consisted of O0603 1 15 two sheets of a size of 3*4*0.02 cm forming a O0603 1 16 sandwich. Detector was sensitive to fragments with O0603 1 17 A>=16. Heavy reaction fragments were stopped inside O0603 1 18 the Makrofol sheets and could thus be detected in a O0603 1 19 4Pi geometry. O0603 1 20 CORRECTION Performed: Loss of events of about 2% due to removal O0603 1 21 of the detector material in the course of chemical O0603 1 22 treatment. O0603 1 23 Negligible: Casual coincidences between two individualO0603 1 24 tracks and an individual track with binary events. O0603 1 25 COMMENT - By Authors- Binary fission induced by high-energy O0603 1 26 particles is defined as a decay of nucleus into two O0603 1 27 fragments of approximately equal masses with an angle O0603 1 28 between their emission directions larger than 90 degr. O0603 1 29 Events with three tracks are defined as ternary fissionO0603 1 30 regardless of the mechanism of their production. O0603 1 31 HISTORY (19971206C) AP: By Khlopin's Institute.
