Abstract

Titanium-45 with a half-life of 3.09 hours decays by emission of positrons (85%) and the electron capture process (15%).These properties make this radionuclide useful in the diagnosis of tumors by positron emission tomography. In this study, after having considered the excitation functions for the ⁴⁵Sc(p, n)⁴⁵Ti reaction using TALYS and ALICE/ASH codes and after the comparison with other experimental data, ⁴⁵Ti was produced by dint of the pressing method and a newly designed and manufactured shuttle and capsule, resulting in an experimental yield of 403.3 MBq/µAh. Essential target thickness and physical yield were calculated. The scandium oxide target was irradiated at a 20 µA current and a 21 MeV proton beam energy for 1 hour.

Key words: ⁴⁵Ti, ⁴⁵Sc, proton, excitation function, physical yield
