Abstract

Activation cross sections of the medically interesting radionuclide ⁴⁵Ti were investigated in the deuteron-induced reaction on ⁴⁵Sc. ⁴⁵Ti can be produced in a radioactive-contamination-free form in the ⁴⁵Sc(d,2n)⁴⁵Ti reaction below 15 MeV deuteron energy. The stacked foil activation technique and γ-ray spectrometry were used to determine the cross sections. The physical yield of ⁴⁵Ti was deduced from the measured cross sections.

Keywords: Cross section; Deuteron irradiation; Excitation function; Physical yield; Scandium-45; Titanium-45.
