The targets were prepared on 93Nb or 165Ho O2404 1 16 catcher foils of 2.5 mg/cm2 thickness. O2404 1 17 DETECTOR (SIBAR) Two 1000 um Si surface barrier detectors, O2404 1 18 placed at +/- 20 degrees with respect to the beam O2404 1 19 axis to monitor beam intensity O2404 1 20 (SILI) Two Si(Li) detectors with diameter of 16 mm, O2404 1 21 and an active thickness of 5 mm were used for O2404 1 22 activity measurements. Both detectors had 50 microns O2404 1 23 thick Be windows, and were surrounded by 5 cm thick O2404 1 24 lead shielding. O2404 1 25 METHOD (EXTB,SITA,ACTIV,EDEG,XSPEC,STTA) The beam first O2404 1 26 crossed a thin Au foil (100 ug/cm2) before hitting O2404 1 27 the target. Both single target and stacked target O2404 1 28 irradiations were used to measure the excitation O2404 1 29 function of 6Li + 120Sn and 7Li + 119Sn. In both O2404 1 30 cases, the compound nucleus 126I is created, which O2404 1 31 produces 124I and 123I isotopes via 2n and 3n O2404 1 32 evaporation channels. Both isotopes then decay via EC O2404 1 33 into tellurium, which is followed by emission of O2404 1 34 atomic x-ray lines. O2404 1 35 In addition, production cross sections for 120Sb were O2404 1 36 also measured by detecting the characteristic x-rays O2404 1 37 of Sn. O2404 1 38 ANALYSIS In the analysis, only the k-alpha lines of Te and Sb O2404 1 39 were used, taking into account the corresponding O2404 1 40 fluorescence probabilities. The yields were O2404 1 41 determined from the analysis of the measured activity O2404 1 42 as function of the time. O2404 1 43 ERR-ANALYS (ERR-T) Final uncertainty of the data, combining O2404 1 44 statistical and systematic uncertainties. O2404 1 45 The systematic uncertainty includes the following O2404 1 46 components: O2404 1 47 (ERR-1) x-ray detection efficiency (5%) O2404 1 48 (ERR-2) target thickness (2%) O2404 1 49 (ERR-3) k-alpha fluorescence probability for I-123 (2%)O2404 1 50 (ERR-4) k-alpha fluorescence probability for I-124 (5%)O2404 1 51 ADD-RES (COMP) The results were compared with theoretical O2404 1 52 predictions from coupled channels calculations with O2404 1 53 the FRESCO code.
