Yield and excitation function measurements of some nuclear reactions on natural thallium induced by protons leading to the production of medical radioisotopes ²⁰¹Tl and ²⁰³Pb

Keywords: Natural thallium, Excitation function, Activation technique, Medical radioisotope, Proton

Excitation functions for ²⁰¹Pb, ^202mPb, ²⁰³Pb and ^204mPb radionuclides which are formed via proton induced reactions with natural thallium target have been measured from their respective threshold (E_thr) to 27.5 MeV using activation technique. Natural copper foils were used to monitor the cyclotron beam. The integral yields (MBq/μA h) of the produced radionuclides were calculated from the measured excitation functions. The optimum proton energy range for the production of ²⁰³Pb with low amount of impurities is (16–10 MeV) after 5 h of EOB. The experimental cross-sections for ^natTl(p,xn) reactions were compared with the cross-sections recommended by the IAEA and with earlier published data when it was possible.
