Production and separation of radioactive astatine isotopes in the $$^7$$Li+$$^{nat}$$Pb reaction

To promote utilization of a radioactive nuclide $$^{211}$$At which draws increasing attention as a promissing $$alpha$$-emitter for targeted alpha therapy, we have measured production cross sections of astatine isotopes in the 29-57 MeV$$^7$$Li+$$^{nat}$$Pb reaction using the tandem accelerator of JAEA-Tokai, providing nuclear data for production. For pharmaceutical study and so on, beside, we have developed a new separation procedure based on a dry-distillation method which separates carrier free astatine isotopes from lead targets with high radiochemical and chemical purity and high yields.
