Medically relevant radioisotope production through low energy heavy ion reactions
摘要
The emission of auger electrons from 161Ho makes it as a potential candidate for Auger electronic therapy. Despite several methods for its production are proposed, it remains scarcely available. Most of the direct methods using low-energy protons and deuterons beams result in a high content of radionuclidic impurities. Hence, an alternative method for the production of 161Ho has been proposed. Experimental excitation functions in 16O induced reactions were measured with the activation method in the 69–100 MeV energy range on 154Sm targets. To measure the cross-section data for producing 161Ho, the stacked foil irradiation method along with high-resolution gamma-ray spectrometry was employed. The experimental data are compared with results of PACE4 and EMPIRE-3.2.2 theoretical codes. It was observed that the 161Ho radioisotope is produced via incomplete fusion. The production route suggested has no impurities of Holmium isotopes.
