Tech., Stockholm) ; Barrientos, D (CERN) ; Bazzacco, D (INFN, Padua) ; Bednarczyk, P (Cracow, INP) et al.
The γ -ray emission from the nuclei $^{62,64}$Fe following Coulomb excitation at bombarding energy of 400-440 AMeV was measured with special focus on E 1 transitions in the energy region 4-8 MeV. The unstable neutron-rich nuclei $^{62,64}$Fe were produced at the FAIR-GSI laboratories and selected with the FRS spectrometer. [...]

The neutron-rich $^{213}$Pb isotope was produced in the fragmentation of a primary 1 GeV $A$ $^{238}$U beam, separated in FRS in mass and atomic number, and then implanted for isomer decay $\gamma$-ray spectroscopy with the RISING setup at GSI. A newly observed isomer and its measured decay properties indicate that states in $^{213}$Pb are characterized by the seniority quantum number that counts the nucleons not in pairs coupled to angular momentum $J=0$.

New spectroscopic information on $^{211,213}\mathrm{Tl}$: A changing structure beyond the $N=126$ shell closure
/ 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 $^{209}\mathrm{Tl}$. [...]

(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 $A=150$. [...]

Two-proton decay of the unbound $ T_{z} =-2$ nucleus$^{16}$Ne , produced in one-neutron knockout from a 500 MeV/u$^{17}$Ne beam, has been studied at GSI. The ground state, at a resonance energy 1.388(15) MeV, ( $ \Gamma =0.082(15)$ MeV) above the$^{14}$O +p+p threshold, and two narrow resonances at $ E_{r} =3.220(46)$ MeV and 7.57(6) MeV have been investigated.

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. [...]

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. [...]
