/ Ghys, L (Leuven U. ; SCK-CEN, Mol) ; Andreyev, A N (York U., England ; JAEA, Ibaraki ; West Scotland U.) ; Huyse, M (Leuven U.) ; Van Duppen, P (Leuven U.) ; Sels, S (Leuven U.) ; Andel, B (Comenius U.) ; Antalic, S (Comenius U.) ; Barzakh, A (St. Petersburg, INP) ; Capponi, L (West Scotland U.) ; Cocolios, T E (CERN ; Manchester U.) et al.
Low-energy β-delayed fission of At194,196 and Fr200,202 was studied in detail at the mass separator ISOLDE at CERN. The fission-fragment mass distributions of daughter nuclei Po194,196 and Rn202 indicate a triple-humped structure, marking the transition between asymmetric fission of Hg178,180 and symmetric fission in the light Ra-Rn nuclei.

$\beta$-delayed fission and $\alpha$ decay of $^{196}$At
/ Truesdale, V L (York U., England) ; Andreyev, A N (York U., England ; JAEA, Ibaraki ; West Scotland U.) ; Ghys, L (Leuven U. ; SCK-CEN, Mol) ; Huyse, M (Leuven U.) ; Van Duppen, P (Leuven U.) ; Sels, S (Leuven U.) ; Andel, B (Comenius U.) ; Antalic, S (Comenius U.) ; Barzakh, A (St. Petersburg, INP) ; Capponi, L (West Scotland U.) et al.
A nuclear-decay spectroscopy study of the neutron-deficient isotope At196 is reported where an isotopically pure beam was produced using the selective Resonance Ionization Laser Ion Source and On-Line Isotope Mass Separator (CERN). The fine-structure α decay of At196 allowed the low-energy excited states in the daughter nucleus Bi192 to be investigated. [...]

A study of the $^{180}\mathrm{Hg}$ decay chain performed at the CERN-ISOLDE facility has allowed the ground-state–to–ground-state α decay of $^{180}\mathrm{Pt}$ to be investigated. A more precise α-decay branching ratio of $b_{\alpha}$ $(^{180}\mathrm{Pt})=0.52(5)$% has been deduced. [...]

Change in structure between the $I = 1/2$ states in $^{181}$Tl and $^{177,179}$Au
/ Cubiss, J G (York U., England ; CERN) ; Barzakh, A E (Kurchatov Inst., Moscow) ; Andreyev, A N (York U., England ; JAERI, Tokai ; CERN) ; Al Monthery, M (York U., England) ; Althubiti, N (Manchester U.) ; Andel, B (Comenius U.) ; Antalic, S (Comenius U.) ; Atanasov, D (Heidelberg, Max Planck Inst.) ; Blaum, K (Heidelberg, Max Planck Inst.) ; Cocolios, T E (Leuven U. ; Manchester U. ; CERN) et al.
The first accurate measurements of the $\alpha$-decay branching ratio and half-life of the $I^{\pi}=1/2^+$ ground state in $^{181}$Tl have been made, along with the first determination of the magnetic moments and $I=1/2$ spin assignments of the ground states in $^{177,179}$Au. The results are discussed within the complementary systematics of the reduced $\alpha$-decay widths and nuclear $g$ factors of low-lying, $I^{\pi}=1/2^+$ states in the neutron-deficient lead region.

Inverse odd-even staggering in nuclear charge radii and possible octupole collectivity in $^{217,218,219}\mathrm{At}$ revealed by in-source laser spectroscopy
/ Barzakh, A E (St. Petersburg, INP) ; Cubiss, J G (York U., England) ; Andreyev, A N (York U., England ; JAEA, Ibaraki ; CERN) ; Seliverstov, M D (St. Petersburg, INP ; York U., England) ; Andel, B (Comenius U.) ; Antalic, S (Comenius U.) ; Ascher, P (Heidelberg, Max Planck Inst.) ; Atanasov, D (Heidelberg, Max Planck Inst.) ; Beck, D (Darmstadt, GSI) ; Bieroń, J (Jagiellonian U.) et al.
Hyperfine-structure parameters and isotope shifts for the 795-nm atomic transitions in $^{217,218,219}$At have been measured at CERN-ISOLDE, using the in-source resonance-ionization spectroscopy technique. Magnetic dipole and electric quadrupole moments, and changes in the nuclear mean-square charge radii, have been deduced. [...]

New type of asymmetric fission in proton-rich nuclei
/ Andreyev, A N (Leuven U. ; West Scotland U. ; Scottish U. Research Reactor Ctr.) ; Elseviers, J (Leuven U.) ; Huyse, M (Leuven U.) ; Van Duppen, P (Leuven U.) ; Antalic, S (Comenius U.) ; Barzakh, A (St. Petersburg, INP) ; Bree, N (Leuven U.) ; Cocolios, T E (Leuven U.) ; Comas, V F (Darmstadt, GSI) ; Diriken, J (Leuven U.) et al.
A very exotic process of ${\beta}$-delayed fission of $^{180}$Tl is studied in detail by using resonant laser ionization with subsequent mass separation at ISOLDE (CERN). In contrast to common expectations, the fission-fragment mass distribution of the post-${\beta}$-decay daughter nucleus $^{180}$Hg (N/Z=1.25) is asymmetric. [...]

(Liverpool U.) ; Cocolios, T.E. (CERN ; Manchester U.) et al.
Background: Shape coexistence in heavy nuclei poses a strong challenge to state-of-the-art nuclear models, where several competing shape minima are found close to the ground state. A classic region for investigating this phenomenon is in the region around $Z=82$ and the neutron mid-shell at $N=104$. [...]
