Özet

Photonuclear reactions are important tools in the understanding of the nucleus. These reactions are also interesting for realizing the element creation processes in stellar environment. The use of bremsstrahlung photons generated from clinic linear accelerator is practical for performing these type of reactions. In this study, the bremsstrahlung photons with endpoint energy of 18 MeV have been used for activating gallium target material. After irradiation, the transition energies and half-lives associated with the decay of Ga-68, Ga-70 and Ga-72 isotopes have been determined The values obtained for half-life of Ga-68, Ga-70 and Ga-72 isotopes are 67.5 +/- 0.9 min, 21.1 +/- 0.9 min and 13.8 +/- 0.4 h, respectively. It has been seen that the values are consistent with the present literature values. In addition, the new measurements of gamma-ray energies for transition energies have been obtained comparable to the literature values with good uncertainties.

reactions are also interesting for realizing the element creation processes in stellar environment. The use of bremsstrahlung photons generated from clinic linear accelerator is practical for performing these type of reactions. In this study, the bremsstrahlung photons with endpoint energy of 18 MeV have been used for activating gallium target material. After irradiation, the transition energies and half-lives associated with the decay
of 68Ga, 70Ga and 72Ga isotopes have been determined The values obtained for halflife of 68Ga, 70Ga and 72Ga isotopes are 67.5±0.9min, 21.1±0.9min and 13.8±0.4h,
respectively. It has been seen that the values are consistent with the present literature
values. In addition, the new measurements of gamma-ray energies for transition nergies
have been obtained comparable to the literature values with good uncertainties.
