Estimated yields of cyclotron-produced isotopes

Abstract

Production yields of all the isotopes, with Z = 20 to >92, under bombardment with protons, deuterons and alphas of up to 36 MeV, have been estimated using empirically constructed excitation functions and our simplified method. Results are presented in graphical form, from which the production yield of any isotope in the aforementioned range can be directly obtained for an infinitely thick (stopping the incoming beam completely), moderately thick or even a thin target under given irradiation conditions. These yields would not only help to select the best reaction to produce a particular isotope and help in minimizing the losses due to further processing of the isotopes but would also provide an indication of the unwanted activities which are also being produced simultaneously.
