$\beta$-delayed neutron emission is a common and dominating decay process for most of the neutron-rich nuclei far from the stability line. Experimental investigations on $\beta$-delayed neutrons are of great significance in a large variety of fields, including nuclear physics, astrophysics, and industrial applications. First, it is a sensitive probe to the $\beta$-decay feedings above neutron...

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...

The sensitivities of the r-process rare-earth peak abundances to nuclear masses and beta-decay half-lives have been studied in different astrophysical scenarios. The most impactful nuclei are identified by varying nuclear masses and beta-decay half-lives, respectively. The impacts of nuclear mass as well as β-decay rate of an individual nucleus on the r-process rare-earth peak abundances are...

Exploring the heavy neutron-rich region around and beyond $N=126$ is one of the major aims of nuclear facilities worldwide. The foremost reason is understanding the nucleosynthesis of the heaviest elements existing in nature, formed only by the rapid neutron-capture process. At the third waiting point, the only observable measured systematically up to date ---some $\beta$ half-lives near...
