Three irradiations D426700100025 were performed, one in iThemba LABS in Faure, South D426700100026 Africa and two in Chiba, Japan. At iThemba LABS, the D426700100027 stack consisted of high-purity Gd foils of 25.2 D426700100028 mg/cm2 thickness, 28.9 mg/cm2 thick Cu degrader foils, D426700100029 high-purity Al foils of 3.24 mg/cm2 thickness and Ti D426700100030 foils of 11.5 mg/cm2 thickness were used as monitor D426700100031 foils. The stack was bombarded in an accurately D426700100032 calibrated Faraday chamber mounted at an external D426700100033 beam line. The beam was 4 mm in diameter. The average D426700100034 beam current was 50 nA and the irradiation time was 3 D426700100035 h. The irradiation was done in vacuum with a beam D426700100036 energy of nominally 66.0 MeV. At NIRS, the first D426700100037 stack consisted of 17 high-purity Gd foils of 18.49 D426700100038 mg/cm2 thickness and Co 235.85 and 239.41 mg/cm2 and D426700100039 Au 100.69 mg/cm2 degrader foils. The Co foils were D426700100040 used above 32 MeV and Au below 32 MeV. Ti foils of D426700100041 4.58 mg/cm2 thickness were used as monitor foils. The D426700100042 second stack consisted of 9 high-purity Gd foils of D426700100043 which the first five were 18.49 mg/cm2 thick and the D426700100044 next four were 6.8 mg/cm2 thick. Only Au degrader of D426700100045 100.69 mg/cm2 were used in this stack. Ti monitor D426700100046 foils of 14.08 mg/cm2 were used. Both stacks were D426700100047 irradiated with beam of 4 mm in diameter at beam D426700100048 energies of 70.2 and 30.1 MeV. Due to the window foil D426700100049 the nominal incident energies on the stacks had D426700100050 slightly degraded values of 66.7 and 29.4 MeV. The D426700100051 first irradiation lasted for 1.5 h at an average beam D426700100052 current of 50 nA. The second irradiation lasted for D426700100053 3.8 h with an average beam current of 70 nA.

D426700100061 (EN-ERR) The uncertainty in energy of each measured D426700100062 data point was estimated from the uncertainty in D426700100063 incident beam energy, foil thickness and energy D426700100064 straggling in the stack. D426700100065 (ERR-T)The total uncertainties in the measured D426700100066 cross sections were obtained by summing all the D426700100067 contributing uncertainties in quadrature and are D426700100068 expressed with a 1sigma (68%) confidence level.
