In this work, the $\beta$-stable region for Z $\geq$ 90 is proposed. The calculated $\beta$-stable nuclei in the $\beta$-stable region are in good agreement with the ones obtained by M\"{o}ller \emph{et al}.. The half-lives of the nuclei…
$Background:$ Previous measurements of $\beta$-delayed neutron emitters comprise around 230 nuclei, spanning from the $^{8}$He up to $^{150}$La. Apart from $^{210}$Tl, with a minuscule branching ratio of 0.007\%, no other neutron emitter is…
