Our research purpose is to measure the 7Be(d, p) reaction to shed light on the 7Li problem in the Big-Bang Nucleosynthesis. We are developing an unstable 7Be target for a high-resolution measurement of the 7Be(d, p)8Be reaction. We plan to compare two methods to produce the 7Be target: (1) Activation method, and (2) Implantation method. We performed an activation method experiment at the Van de Graaff at Osaka University, and obtained the cross-section data in December 2015. We continue the development of the activation target method to obtain more accurate data at the Tandem Electrostatic Accelerator, Kobe University. The first trial of the target production experiment at Kobe was in March 2018, and we could produce 3×1012 7Be target in 7 mm2. The (d, p) reaction measurement is scheduled in August 2018. We have also made a 7Be target with the implantation method at CRIB, Center for Nuclear Study, University of Tokyo in 2016. We could produce 1012 7Be target in 7 mm2 after a development for the high intensity 7Be beam at CRIB in 2017. We had the target implantation experiment in April 2018. An experiment to measure the (d, p) reaction with the implanted target was done in June 2018 at Japan Atomic Energy Agency, tandem facility. The result will be reported and discussed.
