Experimental determination of the energy levels of 159Gd via photonuclear reaction

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. The experimental results have been compared with the NUDAT database
