The detectors were D042500100020 arranged on the inner faces of two cubes, four on each D042500100021 face, completely surrounding the target. D042500100022 METHOD (COINC) The identification of the fission fragments wasD042500100023 based on their energy and on the geometry of the D042500100024 emission. D042500100025 ERR-ANALYS (ERR-S) Statistical error D042500100026 (ERR-SYS) the overall systematic uncertainty (from the D042500100027 total beam irradiation, target thickness, and D042500100028 efficiency measurement) is estimated to be around 17%. D042500100029 CORRECTION To obtain the angular distributions, the detected D042500100030 yields were corrected for the detection efficiency of D042500100031 each ring in the corresponding angular region, as D042500100032 measured using the calibrated a source (thus using the D042500100033 approximation of a uniform distribution of the light D042500100034 charged particles in each ring).
