Resonant Photonuclear Reactions for Isotope Transmutation

Abstract

Coherent photonuclear isotope transmutation (CPIT) produces exclusively\nradioactive isotopes (RIs) by coherent photonuclear reactions via E1 giant\nresonances. Photons to be used are medium energy photons produced by laser\nphotons backscattered off GeV electrons. The cross sections are as large as 0.2\n- 0.6 b, being independent of individual nuclides. A large fraction of photons\nis effectively used for the photonuclear reactions, while the scattered GeV\nelectrons remain in the storage ring to be re-used. CPIT with medium energy\nphotons provides specific/desired RIs with the high rate and the high density\nfor nuclear science, molecular biology and for nuclear medicines.\n
