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

Abstract

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 68 Ga, 70 Ga and 72 Ga isotopes have been determined The values obtained for halflife of 68 Ga, 70 Ga and 72 Ga 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.

“…There can be found several attempts to carrying out to reliable photonuclear data (Dietrich and Berman, 1988 and references there in) and Extreme Light Infrastructure -Nuclear Physics (ELI-NP) facility has a perspective for this task (Filipescu et al, 2015). Beside, we have already started to contribute some PNR data to the literature with our simple PNR system (Akkoyun et al, 2016;Bayram et al, 2016;Bayram and Akkoyun, 2018) because we use high efficiency gamma ray detector with respect to the used in the earlier studies. This opens the way to contribution new data in literature.…”

Photonuclear Reaction Results of Energy Levels of Iodine Isotopes

“…In the present day, different methods to study nuclear reactions are available. The clinical linear accelerator (cLINAC) is one of them and has attracted much attention in nuclear physics experiments in recent years [2][3]. Mohr et al [4] have performed 197 Au(γ,n) 196 Au reaction by using a cLINAC.…”
