O095600100019 (20030515U) Last checking has been done. O095600100020 SAMPLE Copper, thickness 0.205 g/cm**2, was used as a target O095600100021 DETECTOR (SCIN) Two large plastic scintillation detectors O095600100022 having dimensions of 80-mm vertically and 200-mm O095600100023 horizontally, with thicknesses of 3 and 5-mm for at theO095600100024 central image plane for Pb and U,reapectivily, and 5 mmO095600100025 at the exit of the spectrometer in both cases. O095600100026 FACILITY (SYNCH,2GERGSI) Heavy-ion synchrotron. O095600100027 (FRS,2GERGSI) Fragment separator. O095600100028 METHOD (TOF) O095600100029 (BCINT) The number of beam particles hitting the O095600100030 target was determined by a second-electron transmissionO095600100031 monitor. The absolute accuracy of this monitor is O095600100032 estimated to be 4% for the Pb-208 beam and 7% for the O095600100033 U-238 beam. O095600100034 (SITA) O095600100035 (ASEP) O095600100036 STATUS (CURVE) By CAJAD O095600100037 CORRECTION -By authors. In order to determine the production crossO095600100038 sections, the following corrections had to applied: O095600100039 1. The ion-optical transmission was calculated. The O095600100040 detector efficiency was measured to be 100%. O095600100041 2. Fragments which are produced in the target may laterO095600100042 be destroyed in the target or in the energy degrader byO095600100043 secondary reactions which can be divided into nuclear O095600100044 reactions and electromagnetic dissociation processes. O095600100045 The loses amounted typically to 2% in the copper O095600100046 target, and 40-48% in the aluminum energy degrader. O095600100047 3. Fragments may also be produced by secondary O095600100048 reactions of other fragments. This contribution to theO095600100049 observed counting rate was calculated for each measuredO095600100050 reaction product and found to be less than a few tenthsO095600100051 of a percent in all cases. O095600100052 4. The dead-time was measured by separately counting O095600100053 the detector events and the events accepted by the O095600100054 data-acquisition system. The correction varied betweenO095600100055 2% and 50%. O095600100056 ADD-RES (COMP) Abrasion-ablation model. O095600100057 ERR-ANALYS (ERR-T) The uncertainty is shown by authors.
