Neutron capture rate on neutron-rich nuclei is one of the most uncertain nuclear physics parameters to understand the r-process nucleosynthesis in the universe. According to the network simulation of the nucleosynthesis, the neutron capture on $^{130}{\rm{Sn}}$ significantly affects the final abundances of the r-process. To reduce the uncertainty, we performed the experiment to study the...
Our research goal is to measure the cross-section of the $^{7}$Be($d$, $p$) reaction in search of a solution to the cosmological $^{7}$Li problem (CLP). The CLP is the overestimation of primordial $^{7}$Li abundance in the standard Big-Bang nucleosynthesis (BBN) model compared to observed abundances, a major unresolved problem in modern astrophysics. A recent theoretical BBN model emphasized...
Nuclear reactions in the $\alpha$p-process including the ${}^{26}$Si($\alpha$, p)${}^{29}$P are important for the nucleosynthesis in X-ray bursts. However, there are not sufficient experimental data of the reactions because radioactive-isotope (RI) beam is required to perform the experiment and the cross section is low. In order to acquire the sufficient nuclear data of the...
The p-9Be reactions play a key role in accurate prediction of primordial abundance of beryllium, and its abundance can be used to exquisitely probe the nucleosynthesis and mixing mechanism of stars. In the present work, astrophysical S(E) factors of the 9Be(p,d)8Be and 9Be(p,α)6Li reactions have been obtained from thick-target yield Yield(Ei) for proton energies from 18 to 100 keV. A full...
