New test of modulated electron capture decay of hydrogen-like $^{142}$Pm ions: precision measurement of purely exponential decay / FRS-ESR Collaboration
An experiment addressing electron capture (EC) decay of hydrogen-like $^{142}$Pm$^{60+}$ ions has been conducted at the experimental storage ring (ESR) at GSI. The decay appears to be purely exponential and no modulations were observed. [...]

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

(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 / Caballero-Folch, R. ; Domingo-Pardo, C. ; Agramunt, J. ; Algora, A. ; Ameil, F. ; Arcones, A. ; Ayyad, Y. ; Benlliure, J. ; Borzov, I.N. ; Bowry, M. et al.
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. [...]

High-resolution measurement of the time-modulated orbital electron capture and of the $\beta^+$ decay of hydrogen-like $^{142}$Pm$^{60+}$ ions / Two-Body-Weak-Decays Collaboration
The periodic time modulations, found recently in the two-body orbital electron-capture (EC) decay of both, hydrogen-like $^{140}$Pr$^{58+}$ and $^{142}$Pm$^{60+}$ ions, with periods near to 7s and amplitudes of about 20%, were re-investigated for the case of $^{142}$Pm$^{60+}$ by using a 245 MHz resonator cavity with a much improved sensitivity and time resolution. We observed that the exponential EC decay is modulated with a period $T = 7.11(11)$s, in accordance with a modulation period $T = 7.12(11)$ s as obtained from simultaneous observations with a capacitive pick-up, employed also in the previous experiments.

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. [...]
