Abstract
For the activation of the target nucleus, bremsstrahlung photons generated in a medical linear accelerator can be used. Due to particle separation energy limitations for low photon energies in the giant resonance region ( similar to 18MeV), the reaction exit channels are restricted to the ejection of one or two particles only. Thus, the gamma spectrum is relatively clear, and the use of ancillary detectors coupled to HPGe is not highly needed. In this study, the bremsstrahlung photons have been used for the activation of the titanium target. Sc46-48 isotopes are observed from the natural titanium target via photo-proton reactions. Decay radiations from the isotopes and half-life of Sc-47 which is from the most abundant natural titanium have been determined consistent with the literature values.
