Description

Understanding neutron-rich unstable nuclei is crucial for investigating the r-process nucleosynthesis. In particular, the $\beta$ decay of the $N = 126$ isotones is decisive for the production of the third peak, including gold and platinum. In this talk, based on nucleosynthesis uncertainty calculations, I will discuss the possibility of addressing the "missing gold problem" in the galactic chemical evolution study by improving the $\beta$-decay half-live of $N=126$ nuclei.
