Abstract
We studied the production of medically applicable scandium radioisotopes through the natTi(p,x) reactions with in the energy range of their threshold to 44 MeV. The excitation functions of natTi(p,x) reactions and thick target yield of scandium radioisotopes (43,44m,44g,46,47,48Sc) and by-product (48V) were also measured. For this purpose, pure thin titanium foils were stacked and irradiated with different proton energies by using the MC-50 cyclotron at the Korea Institute of Radiological and Medical Sciences (KIRAMS), Korea. The data acquisition and activation analysis was performed by using an off-line γ-ray spectrometry technique. The measured results were compared with literature data as well as the data from the TENDL-2017 library based on TALYS-1.9 code. The integral yields for the thick target using the measured cross section were also presented. The results reveal that natTi(p,x) reaction is one of the best route for the production of medical radioisotopes of 43,44m,44g,46,47,48Sc with controllable impurity of 48V.
