Energy level and half-life determinations from photonuclear reaction on Ga target

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[Formula: see text]MeV have been used for activating gallium target material. After irradiation, the transition energies and half-lives associated with the decay of [Formula: see text], [Formula: see text] and [Formula: see text] isotopes have been determined The values obtained for half-life of [Formula: see text], [Formula: see text] and [Formula: see text] isotopes are [Formula: see text][Formula: see text]min, [Formula: see text][Formula: see text]min and [Formula: see text][Formula: see text]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.
