Large-Scale Calculations of ${\hat{I}}^2$-Decay Rates and Implications for $r$-Process Nucleosynthesis

A. Ravlić, Y. Saito, W. Nazarewicz

Nuclear ${\hat{I}}^2$ decay is a key element of the astrophysical rapid neutron capture process ($r$-process). In this paper, we present state-of-the-art global ${\hat{I}}^2$-decay calculations base…
