Effect of Finite-Temperature $β$-Decay Rates on the Rapid Neutron Capture Process
$β$-decay is known to play an essential role in the rapid neutron capture process ($r$-process) during $(n, γ) \leftrightarrow (γ, n)$ equilibrium and freeze-out when the neutron-rich nuclei decay back to stability. Recent systematic theoretical studies on $β$-decay at finite temperature indicated that under hot conditions ($T\sim10$~GK), a significant acceleration of $β$-decay rates is expected, especially for nuclei near stability. This corresponds to the early stage of the $r$-process. …
