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. D426300100033

ERR-ANALYS (EN-ERR)The uncertainty on the median energy in the D426300100036
foils increases along the stack and includes the D426300100037
cumulative effects the uncertainty of incident beam D426300100038
energy (+-0.2 MeV), uncertainty on stopping in each D426300100039
foil due to thickness variation (5%) and straggling D426300100040
effects. 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. D426300100049
