Our research goal is to measure the 7 Be( d, p ) reaction to shed light on the 7 Li problem in the Big-Bang Nucleosynthesis. We are developing an unstable 7Be target for a high-resolution measurement of the 7 Be( d, p ) 8 Be reaction. We plan to compare two methods to producethe 7 Be target: (1) Activation method , and (2) Implantation method . We performed an activation methodexperiment at the Van de Graaff at Osaka University, and obtained the cross-section data. A second experiment to obtain more accurate data will take place at the Tandem Electrostatic Accelerator, Kobe University. We have also made a 7 Be target with implantation method at CRIB, Center for Nuclear Study, Univer-sity of Tokyo. An experiment to measure the ( d, p ) reaction with the implanted target is scheduled for 2018 at Japan Atomic Energy Agency, tandem facility.
