Description
Unlocking the origins of the third r-process peak requires a broader understanding of the neutron-rich nuclei near the N=126 shell closure. To validate theoretical predictions and improve r-process calculations, new experimental data on these exotic isotopes are critical. This talk reports on measurements of half-lives and β-delayed neutron emission probabilities ($P_n$) for neutron-rich nuclei across the N=126 shell closure, performed during the BRIKEN campaign at RIBF, including the first measurements of 40 isotopes. The implications on nuclear structure and impact on nucleosynthesis will be discussed.
