Study of Stellar Reactions with Low-Energy RI Beams in Nuclear Astrophysics
Nuclear reactions at low energies play a crucial role for the evolution of
the universe in terms of synthesis of elements and production of energy.
Thus, it is of critical importance to study such reactions to understand
the evolution and various stellar phenomena, although very few of them were
investigated in detail so far. Especially, under high-temperature and
high-density condition, successive nuclear reactions involve various unstable
nuclei. Such astrophysical reactions can be directly investigated with
low-energy RI beams. CNS has successfully introduced an extensive low-energy
in-flight RIB separator, called CRIB, in the RIKEN accelerator facility under
CNS-RIKEN joint venture. New developments in ECR ion sources and the AVF
cyclotron enhanced such activities in energy as well as the beam intensity.
We may discuss recent development in nuclear astrophysics including some hot
results obtained with using RI beams from CRIB. Perspectives in the field will
be also discussed, especially those to be pursued at the RIBF, the RI beam
factory project, which is under construction and provides the first beam in
2006 at RIKEN.
