O095500100017 SAMPLE The Pb, Cu and Al-targets located behind the O095500100018 fragment recoil separator. The ions U-238 were O095500100019 particly stripped by a thin copper foil thickness 205 O095500100020 mg/cm**2 placed at the target position of the fragment O095500100021 separator. O095500100022 DETECTOR (IOCH) Two four stage multiple sampling ionization O095500100023 chambers, located before and after the target- O095500100024 MUSIC1 and MUSIC2 were used to identify the nuclear O095500100025 charge. With MUSIC1 the primary U-ions were counted. O095500100026 The MUSIC2 was used either in a standard mode in order O095500100027 to measure the attenuation of the primary beam or to O095500100028 enumerate fission in events from the detection of a O095500100029 pair of ionizing fragments. O095500100030 (SCIN) Two large plastic scintillation detectors O095500100031 located behind the chamber and divided by a narrow O095500100032 horizontal slit in order to let the beam through. O095500100033 FACILITY (SYNCH,2GERGSI) Heavy-ion synchrotron. O095500100034 (FRS,2GERGSI) Fragment separator. O095500100035 METHOD (TOF) Fission fragments are emitted back-to-back O095500100036 isotropically in the projectile frame. The transfer of O095500100037 momentum between the target nucleus and the uranium O095500100038 projectile can be neglected and the fission kinematics O095500100039 is assumed to be same as far an in-flight decay taking O095500100040 place in the target. O095500100041 PART-DET (FF) O095500100042 COMMENT - By authors. Fission events were sorted by different O095500100043 methods- O095500100044 counting the events for which two fragments of O095500100045 intermediate z were detected in music2. O095500100046 Measuring the energy loss of the two fragments. O095500100047 The spectrum of the energy loss for the first fragment O095500100048 of a pair was analyzed. O095500100049 Target-out contributions were subtracted with the threeO095500100050 methods. It reduces the accuracy of the measurement. O095500100051 Together with the uncertainty due to the estimated of O095500100052 unresolved pairs of fragments,the precision ranges fromO095500100053 7% to 10% according to the target.
