Study of secondary implantation of radioisotopes during alpha-particle irradiation

This work presents the recoil and secondary implantation of radioisotopes at different bombarding energies in the range of ~ 13 to ~ 40 MeV by using an α-particle beam of 50 MeV irradiating a stack of Ag, Ni and Ti metal foils. Activation cross-sections for the produce radioisotopes were calculated and confronted with literature data. The implanted activity is presented as a function of the primary beam energy for six produced radioisotopes 57 Ni, 57 Co, 65 Zn, 51 Cr, 48 V and 46 Sc. The use of each of these radioisotopes in engineering experiments based on the nano-thin layer activation is discussed.
