Abstract

Nuclear spectroscopy is an important tool for deeper understanding of nuclear structure as well as for life sciences. In particular huge experimental designs and more complicated systems are used to perform nuclear reactions and observing particles or gamma rays after reactions for studying nuclear science and nuclear technology in many laboratories i.e. GANIL, INFN-LNL, RIKEN. Many students who have just started to master study on nuclear science and nuclear spectroscopy come across some difficulties for understanding how a nuclear reaction is performed and how a particle after nuclear reaction is detected in complicated laboratories. We have some progress on it by using simple photonuclear reaction system. Photonuclear reactions are performed by using energetic bremsstrahlung photons. After bombarding of target with photons target nuclei can emit one/two protons and neutrons depending on energy of photons. Relatively clear spectrum from measurement of residual activity is obtained in this kind of reaction. In our cases we use modified clinical linear electron accelerator (cLINAC) used for radiation therapy before for performing photonuclear reaction. Residual activity is measured after reaction by using HPGe detector system. This compact nuclear reaction mechanism and detection tools with limited budget provide deeper understanding of nuclear experiments for students. Also such a system is useful for studying forensic science, sterilization and meteor analysis. In the present study, some results obtained from our compact system used for performing educational photonuclear reactions are discussed in detail.
