Outline of Final Research Achievements |
We have already studied the production of astatine-211 and have found that melting of the bismuth target was observed by irradiation of 3.5 micro ampere of alpha-beam because of low melting point of bismuth (271.4 °C). In this study, we tried to develop a new solid target system which can produce astatine-211 without melting of the Bi target by irradiation with intensive alpha-beam, and also heat tolerance of the target by using the new target system and chemical separation of astatine-211 from an irradiated target were investigated.
