The typical current recorded was C155500100015 between 200 and 250 nA C155500100016 METHOD (ACTIV) C155500100017 DETECTOR (HPGE) The detection system was composed of two Clover C155500100018 Ge detectors (Clover 1 and Clover 2), each detector C155500100019 having four HPGe crystals C155500100020 SAMPLE Isotopically enriched 112Sn targets in the form of C155500100021 thin self-supporting foils of 2.2mg/cm2 were used for C155500100022 the measurements. The highly enriched (99.60 %) C155500100023 112Sn targets were prepared at Argonne National C155500100024 Laboratory via mechanical rolling. The 112Sn foils C155500100025 were mounted on Ta frames with hole diameters of C155500100026 12.5 mm. The target thickness was determined by C155500100027 Rutherford back scattering (RBS) to be 2.2 +/- C155500100028 0.2 mg/cm2 and was verified at the end of the C155500100029 experiment. C155500100030 ERR-ANALYS The total error of the measured cross section values C155500100031 includes two components: statistical error based on C155500100032 counting statistics of the analyzed gamma-lines C155500100033 (between 0.2 and 25% depending on the bombarding C155500100034 energy) and systematical error based on the C155500100035 errors in the procedural techniques such as the C155500100036 error in the efficiency measurement (2%), the error C155500100037 in the beam current integration (2%), and target C155500100038 thickness (9%).
