Description
Approximately half of our solar system's elements are believed to have been synthesized through the rapid neutron-capture process (r-process), which occurs when a competition between neutron-capture reactions and β-decay takes place in extremely neutron-rich nuclei. Recent multi-messenger observations combining gravitational-wave and electromagnetic signals have provided compelling evidence for r-process nucleosynthesis, including the production of Sr, Y, Te, and lanthanide elements. Meanwhile, precise spectroscopy of metal-poor stars has enabled high-quality r-process elemental abundance data to constrain the physical conditions of the r-process.
In this presentation, we will report on experiments conducted at the Radioactive Isotope Beam Factory (RIBF) to investigate the mechanisms of r-process nucleosynthesis. Additionally, our perspective for future experimental programs will be discussed for potential collaboration opportunities.
