Radioisotope production in target fragmentation with high-energy heavy ions at HIMAC

Abstract

In order to improve utilisation of the multitracer method, two aspects of the method were pursued in this study. The production of radioisotopes from target fragmentation of 197Au nuclei was performed with high-energetic heavy ions of 12C (180, 290, 400 MeV/u) and 4~ (290, 650 MeV/u) at HIMAC facilities. The yields of products were measured by using a thick-target-thickcatcher method and off-line y-ray spectrometry with Ge semiconductor detectors. Besides, a special apparatus for practice of the radioisotope production was designed in application of the tracers for separation of the products from target material with high efficiency and the target material and shape for the design was investigated in a trial examination.
