The targets were prepared on 93Nb or 165Ho O240400100016 catcher foils of 2.5 mg/cm2 thickness. O240400100017 DETECTOR (SIBAR) Two 1000 um Si surface barrier detectors, O240400100018 placed at +/- 20 degrees with respect to the beam O240400100019 axis to monitor beam intensity O240400100020 (SILI) Two Si(Li) detectors with diameter of 16 mm, O240400100021 and an active thickness of 5 mm were used for O240400100022 activity measurements. Both detectors had 50 microns O240400100023 thick Be windows, and were surrounded by 5 cm thick O240400100024 lead shielding. O240400100025 METHOD (EXTB,SITA,ACTIV,EDEG,XSPEC,STTA) The beam first O240400100026 crossed a thin Au foil (100 ug/cm2) before hitting O240400100027 the target. Both single target and stacked target O240400100028 irradiations were used to measure the excitation O240400100029 function of 6Li + 120Sn and 7Li + 119Sn. In both O240400100030 cases, the compound nucleus 126I is created, which O240400100031 produces 124I and 123I isotopes via 2n and 3n O240400100032 evaporation channels. Both isotopes then decay via EC O240400100033 into tellurium, which is followed by emission of O240400100034 atomic x-ray lines. O240400100035 In addition, production cross sections for 120Sb were O240400100036 also measured by detecting the characteristic x-rays O240400100037 of Sn. O240400100038 ANALYSIS In the analysis, only the k-alpha lines of Te and Sb O240400100039 were used, taking into account the corresponding O240400100040 fluorescence probabilities. The yields were O240400100041 determined from the analysis of the measured activity O240400100042 as function of the time. O240400100043 ERR-ANALYS (ERR-T) Final uncertainty of the data, combining O240400100044 statistical and systematic uncertainties. O240400100045 The systematic uncertainty includes the following O240400100046 components: O240400100047 (ERR-1) x-ray detection efficiency (5%) O240400100048 (ERR-2) target thickness (2%) O240400100049 (ERR-3) k-alpha fluorescence probability for I-123 (2%)O240400100050 (ERR-4) k-alpha fluorescence probability for I-124 (5%)O240400100051 ADD-RES (COMP) The results were compared with theoretical O240400100052 predictions from coupled channels calculations with O240400100053 the FRESCO code.
