The titanium foil, at the end of the stack, was used O173400100025
for beam current calibration using the Ti-48(a,n)Cr-51 O173400100026
reaction and for catching the recoil Ga-67 radio- O173400100027
isotopes from the preceding copper foil in order to O173400100028
estimate the recoiled fraction. O173400100029

DETECTOR (HPGE) The energy resolution of the HPGe detector was O173400100031
1.9 keV at E(g)=1332.5 keV Ga-67. O173400100032
ERR-ANALYS Authors appreciated 18% uncertainties for measured O173400100033
cross sections, considering all uncertainties of O173400100034
detector efficiency calibration, target foil thickness,O173400100035
beam current, counting statistics, decay rate and O173400100036
recoil fraction. O173400100037
(EN-ERR).The uncertainty of energy is reported by O173400100038
authors in table. O173400100039
(DATA-ERR).The uncertainty is reported by authors in O173400100040
table. O173400100041
ADD-RES (TTY-C).The yield for Cu-63(a,g) reaction is calculatedO173400100042
using Eq.4(see text) and considering successive thin O173400100043
slices of 1000 A thickness. O173400100044
