D426300100004 AUTHOR (A.Hermanne,S.Takacs,F.Tarkanyi,R.Adam-Rebeles, D426300100005 A.Ignatyuk) D426300100006 INSTITUTE (3HUNDEB,2BLGVUB,4RUSFEI) D426300100007 REFERENCE (J,ARI,70,911,2012) D426300100008 #doi:10.1016/j.apradiso.2012.02.010 D426300100009 FACILITY (CYCLO,2BLGLVN) D426300100010 SAMPLE Flexible carbon foils of surface density 23.4 mg/cm2 D426300100011 Goodfellow, purity 99.8%, nominal thickness 123.3 um D426300100012 (6-C-12,NAT=0.9893) D426300100013 (6-C-13,NAT=0.0107) D426300100014 DETECTOR (HPGE) D426300100015 METHOD (ACTIV,EXTB,EDEG,GSPEC,MOSEP,STTA) Two stacks were D426300100016 irradiated at the external beam line of the CGR90 D426300100017 cyclotron in Louvain la Neuve (LLN, Belgium) with D426300100018 deuterons of 50 MeV incident energy. In exp1, foils D426300100019 were stacked in a 18 times repeated Al-Ti-C-Ti. The D426300100020 Ti foils (10.9 mm thick) also serves as catcher foils D426300100021 for the recoiled reaction products. In exp2 the stack D426300100022 contained beside the carbon foils also Al (49.06 um), D426300100023 Ti (10.9 um), Ni (9.95 um) and Mg (275 um) foils. The D426300100024 irradiation took place under vacuum. The beam current D426300100025 was constant at about 120 nA during the 1.5 h D426300100026 irradiation. The cross-sections were calculated using D426300100027 the activation formula. The decay data taken from the D426300100028 on-line data library NuDat2 based on Evaluated D426300100029 Nuclear Structure Data File (ENSDF), Database version D426300100030 of October 2011. D426300100031 Care was taken to correct the 7Be cross-section D426300100032 measured directly for recoiled fragments.

D426300100041 The overall estimation is an uncertainty of +-0.2 MeV D426300100042 for the first foils, increasing to +-2.5 MeV in the D426300100043 last foil. D426300100044 (DATA-ERR) The uncertainty of the cross-sections were D426300100045 estimated taking the independent relative errors of theD426300100046 linearly contributing components. D426300100047 ADD-RES (TTY-C) Fitted excitation functions were used for D426300100048 determination of integral physical yields.
