Non-destructive and radiochemical determination of the neutron-induced production cross section of I-129 from Te and other neutron-induced cross sections on Te at 14.7 MeV

Cross sections of twelve neutron-induced reactions on tellurium at 14.7 MeV have been determined. Among them are the (n,2n) cross sections for the production of both ¹²⁹Te isomers which were determined using gamma ray spectrometry. These reactions dominate the cosmogenic production of ¹²⁹I in meteoroids and are therefore of special importance. In addition, the neutron-induced cross section on Te at 14.7 MeV for the production of ¹²⁹I was also determined directly by accelerator mass spectrometry (AMS) after radiochemical separation. The results for the production cross section of ¹²⁹I determined by the two methods agree within 5%.
