Description
X-ray bursts are interesting astrophysical phenomena that occur in binary star systems of neutron stars and companion stars. As the results of the X-ray bursts, the heavy elements up to the Sn-Te region can be synthesized within only a few seconds. The $^{26}$Si($\alpha$,$p$)$^{29}$P nuclear reaction rate plays a crucial role in understanding the X-ray burst phenomena, since the reaction rate significantly affects the X-ray light curves and the abundances of heavy nuclei. To estimate the reaction rate at stellar temperatures, the $^{26}$Si + $\alpha$ scattering experiment was performed at Center for the Nuclear Study Radioactive Ion Beam Separator (CRIB) of the University of Tokyo. The 26Si radioactive ion beam was produced through the $^{3}$He($^{24}$Mg,$^{26}$Si)$n$ reaction by In-flight method. The wide energy range in $^{30}$S was investigated by adopting the thick target method. The $^{26}$Si radioactive ion beams were monitored by two PPACs. The recoiling $\alpha$ particles were detected by silicon detector telescope. The detail of experiment will be discussed.
