Simultaneous production of Mg-28 and Ca-47 by high-energy heavy-ion irradiation for applications in biology

摘要

With the aim of preparing carrier-free Mg-28 and Ca-47 simultaneously, Ti, V and Fe targets were examined by irradiating with high-energy ions of C-12, N-14 and O-16 accelerated by the RIKEN Ring Cyclotron. Among the targets, V gave the highest cross section for the formation of both Mg-28 and Ca-47 irrespective of the kind of beams. The cross section for the formation of Mg-28 by the reactions of Ti, V and Fe targets with ion beams increased in the order of C-12
