D437400100012 DETECTOR (HPGE) D437400100013 METHOD (ACTIV,EXTB,EDEG,GSPEC,MOSEP,STTA) D437400100014 Stack1 and stack2 contained ten and eight high purity D437400100015 ytterbium foils, respectively, interloaded with Ti D437400100016 monitor foils. D437400100017 An Al degrader was placed at the front of stack2 to D437400100018 ensure a small energy shift in the successive Yb foils D437400100019 of the two stacks. D437400100020 Incident alpha energy: 39 MeV, D437400100021 beam currents: 137 and 128 nA, D437400100022 irradiation times: 90 min in both cases. D437400100023 No chemical separation. D437400100024 The data acquisition started 1 year after the end of D437400100025 bombardment.

D437400100032 ERR-ANALYS (EN-ERR) The energy uncertainty at the first foil in D437400100033 the stack was estimated to be 0.3 MeV increasing up to D437400100034 1.5 MeV at the last foil due to the energy straggling D437400100035 and the uncertainty on the target thickness. D437400100036 (ERR-T) The uncertainty on the cross sections was D437400100037 determined in the standard way: the linearly D437400100038 contributing independent processes were taken into D437400100039 account by extracting the square root of quadratically D437400100040 summed relative uncertainties, namely: D437400100041 (ERR-1) number of the bombarding particles (7%), D437400100042 (ERR-2) number of the target nuclei (3%), D437400100043 (ERR-3) decay data (3%), D437400100044 (ERR-4) detector efficiency (7%) and D437400100045 (ERR-S,1.0,10.)peak area (1-10%) D437400100046 HISTORY (20171127C) ts D437400100047 (20220506A) VT.
