Energy levels and half-lives of tungsten isotopes obteined by photo-nuclear reaction

Energy levels and half-life are very important to understanding of nuclei structure. Until now, a lot of studies have been made to determine energy levels and half life for nuclei. Most of the studies, Sodium Iodide (NaI) scintillation detectors which have low energy resolution have been used. Semiconductor detectors which have high energy resolution can be used to determine energy levels, half life for nuclei and to obtain accurate and reliable results. Determination of energy levels and half-lives of nuclei include necessary information about the nuclei-nuclei interactions, fission, fusion, transitions of electric and magnetic and production of radioisotope. First photonuclear reaction has been realized by our team in our country. With this experience, we wanted to contribute national and international literature. We have run an experiment to determine the energy levels and half-lives of Tungsten nucleus by using the photonuclear reactions with end-point energy of 18 MeV bremsstrahlung photons, produced by a clinical linear accelerator. As a result of 180W(γ,n)179W and 186W(n, γ)187W photonuclear reactions, the energy levels and half-lives of tungsten isotopes have been determined. The results are in good agreement with the literature values.
