nat Te target / 120g,121,123,124,125,126,128,130 120g,121,123,124,125,126,128,130 I 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 125 I 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 124 I via the nat Te( p, xn) process over the energy range E p = 57 → 53 MeV is 16.7 MBq/µA h. The level of the radionuclidic impurities 125 I and 126 I is, however, rather high, so that it is not meaningful to produce 124 I using nat Te as target material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
