Experimental determination of the energy levels of product nuclei obtained by photonuclear reaction of Nb and I nuclei

The aim of our thesis is to experimentally determine the energy levels of the product nuclei formed with photonuclear reaction of Nb and I nuclei. Determination of energy levels takes an important place in understanding the nucleus structures. With this goal, the samples have been irradiated with 18 MeV maximum energy bremsstrahlung photons using a clinical linear accelerator. As a result of irradiation, 93Nb(γ,n)92mNb, 127I(γ,n)126I ve 127I(n,γ)128I reactions have been observed. The precise energy levels of the products formed by these reactions have been measured by using a high purity germanium (HPGe) detector. The obtained experimental data have been analyzed with the help of gf3 and ROOT programs. Our results have been compared with literature and similarities and differences have been discussed.
