Abstract

In this study, the energy levels of ¹⁵⁹Gd are measured within the framework of the photonuclear reaction. For this aim, bremsstrahlung photons of 18 MeV endpoint energy produced by a clinical linear accelerator are used. The gamma photons emitted from the unstable ¹⁵⁹Gd nucleus are counted by using a high purity Germanium detector. The energy levels are determined with gf3 and ROOT spectrum analysis programs. Finally, all the results are compared with the literature results.

Keywords
