Excitation functions were measured for the formation of 122mCs, 122Xe, 121Xe and 121I from threshold up to 44 MeV in proton induced nuclear reactions on 99.9% enriched 124Xe. The feasibility of 122Xe→122I generator production was investigated. The optimum energy range for the production of 122Xe is Ep = 43 → 35 MeV and the thick target yield amounts to 13.5 mCi/μAh. After an appropriate cooling time a generator containing several hundred mCi of 122Xe could be produced. The daughter 122I could be milked off periodically and would be >99% pure.
