Based on these results and the reliable cross section data available in the literature, the possible thick target yields were also calculated. Two different 68Ga production routes (Cu+alpha and Zn+p) are discussed in detail, especially with regard to the 66Ga and 67Ga contamination levels as a function of the target enrichment level and the incident bombarding energies. Both processes can be used for in-house 68Ga production with low (<1%) 66Ga and/or 67Ga EOB contamination using enriched 68Zn (>80%) or 65Cu (>95%) target. The maximum available yield on 100% enriched 68Zn and 65Cu (irradiation time: 2.25 h; bombarding energy: Ep=20 MeV and Ealpha=18 MeV) is 352.45 mCi/muA (13.04 GBq/muA) and 14.28 mCi/muA (528.36 MBq/muA), respectively.}, pages = {5--11}, title = {Investigation of direct production of 68Ga with low energy multiparticle accelerator}, volume = {100}, year = {2012} }
