Abstract

Excitation functions of the reactions natTe (p, xn)102g,121,123,124,125,126,128,130I were measured from their respective thresholds up to 63 MeV via the stacked foil technique. Thin targets were prepared by a vacuum deposition method. Irradiations were performed using AVF 930 cyclotron at the National Institute of Radiological Sciences. The concord and conflict between our excitation studies and the available literature data are shown. The high values of our cross sections for 125I in comparison to some literature data are discussed. Our cross sections measurements validated some of the literature data obtained using enriched target isotopes. The integral yields of iodine radionuclides were deduced from the measured excitation curves. The estimated yield of 124I via the natTe(p, xn) process over the energy range Ep = 57 → 53 MeV is 16.7 MBq/μA. The level of the radionuclidic impurities 125I and 126I is, however, rather high, so that it is not meaningful to produce 124I using natTe as target material.
