D427600100017 68Zn enriched target material: D427600100018 (30-ZN-64,ENR=0.0044) D427600100019 (30-ZN-66,ENR=0.0037) D427600100020 (30-ZN-67,ENR=0.0027) D427600100021 (30-ZN-68,ENR=0.989) D427600100022 (30-ZN-70,ENR=0.0002) D427600100023 Target backing: 10 micron Ni D427600100024 Target thicknes: 25 microns D427600100025 DETECTOR (HPGE) D427600100026 METHOD (ACTIV,EXTB,EDEG,GSPEC,MOSEP,STTA) Enriched Zn D427600100027 targets were prepared by electro-deposition onto Ni D427600100028 backing. Cu targets were cut as 10 mm diam. The D427600100029 proton and alpha particle irradiations were done at D427600100030 the AVF-930 isochronous cyclotron of NIRS, Chiba. The D427600100031 primary energies were 39.96 MeV with alpha particles D427600100032 and 29.86 MeV with protons. In the case of the alpha D427600100033 experiments 10 and 7 samples, respectively, were D427600100034 activated together with 20 and 30 micron thick Ti D427600100035 foils. For the 68Zn + p study, Cu (thickness: 9 D427600100036 micron) and Au (thickness: 50 micron) foils were used D427600100037 as monitors and degraders, respectively. Irradiation D427600100038 time: 1 hour. Beam intensity: 50 and 100 nA for alpha D427600100039 beam and 50nA for proton beam. D427600100040 (BCINT) Charges obtained by the current integrator D427600100041 ERR-ANALYS (EN-ERR)The uncertainty in the primary beam energy was D427600100042 estimated to be +-0.30 MeV (for alpha particles) and D427600100043 +-0.25 MeV (for protons) but due to the straggling D427600100044 effect and foil thickness uncertainties it increases D427600100045 gradually along the stack and reaches +-1.1 and D427600100046 +-0.8MeV, respectively, at the end of the stacks.
