/ Gottardo, A (INFN, Legnaro ; Padua U.) ; Valiente-Dobón, J J (INFN, Legnaro) ; Benzoni, G (INFN, Milan) ; Morales, A I (INFN, Milan) ; Gadea, A (Valencia U., IFIC) ; Lunardi, S (Padua U. ; INFN, Padua) ; Boutachkov, P (Darmstadt, GSI) ; Bruce, A M (Brighton U.) ; Górska, M (Darmstadt, GSI) ; Grebosz, J (Cracow, INP) et al.
The neutron-rich isotopes $^{211,213}\mathrm{Tl}$, beyond the $N=126$ shell closure, have been studied for the first time in isomer $\gamma$-ray decay, exploiting the fragmentation of a primary uranium beam at the Fragment Separator-Rare Isotopes Investigation at GSI setup. The observed isomeric states in $^{211,213}\mathrm{Tl}$ show a deviation from the seniority-like scheme of $^{209}\mathrm{Tl}$. [...]

$\beta$-decay half-lives and $\beta$-delayed neutron emission probabilities for several isotopes of Au, Hg, Tl, Pb and Bi, beyond $N=126$

(Barcelona, Polytechnic U.) ; Cano-Ott, D. (Madrid, CIEMAT) et al.
$Background:$ 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 measured yet beyond $A=150$. [...]

$\beta$-decay and $\beta$-delayed Neutron Emission Measurements at GSI-FRS Beyond N=126, for r-process Nucleosynthesis
/ Caballero-Folch, R (Barcelona U.) ; Domingo-Pardo, C (Valencia U., IFIC) ; Cortès, G (Barcelona U.) ; Taín, J L (Valencia U., IFIC) ; Agramunt, J (Valencia U., IFIC) ; Algora, A (Valencia U., IFIC ; Debrecen, Inst.

New measurements of very exotic nuclei in the neutron-rich region beyond N=126 have been performed at the GSI facility with the fragment separator (FRS). The aim of the experiment is to determine half-lives and beta-delayed neutron emission branching ratios of isotopes of Hg, Tl and Pb in this region. [...]

First measurement of several $\beta$-delayed neutron emitting isotopes beyond N=126

The $\beta$-delayed neutron emission probabilities of neutron rich Hg and Tl nuclei have been measured together with $\beta$-decay half-lives for 20 isotopes of Au, Hg, Tl, Pb and Bi in the mass region N$\gtrsim$126. These are the heaviest species where neutron emission has been observed so far. [...]

(Surrey U.) ; Calvino, F. (Debrecen, Inst. Nucl. Res.) et al.
The rapid neutron nucleosynthesis process involves an enormous amount of very exotic neutron-rich nuclei, which represent a theoretical and experimental challenge. Two of the main decay properties that affect the final abundance distribution the most are half-lives and neutron branching ratios. [...]
