Recently nuclear medicine therapy using nuclides emitting rays and Auger electrons is gathering attention. rays and Auger electrons have a higher linear energy transfer than rays and are expected to enable the therapy with little damage to normal cells surrounding the tumor. Especially Auger electron emitters have an advantage that their daughter nuclei are less likely to decay compared to ray emitters. We have developed a system to calculate and illustrate nuclide production cross sections and Thick Target Yield (TTY) from various nuclear reactions for contributing to the consideration of wide range of possibilities on production for Auger electron emitters. The developed system can calculate and illustrate arbitrary nuclide production cross sections and TTYs from light particle (, , , , He, , ) injection reactions. The nuclear reaction model calculation code CCONE is used to calculate reaction cross sections. Using this system, we investigated the optimal production method for Auger electron emitters.
