/ Elseviers, J ; Andreyev, A N (York U., England ; JAEA, Ibaraki) ; 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 (CERN ; Leuven U.) ; Comas, V F (Darmstadt, GSI) ; Diriken, J (Leuven U.) et al.
The detailed analysis of the β-delayed fission data of $^{180}$Tl is presented. The experiment was performed by producing a pure beam of $^{180}$Tl by means of highly selective resonance laser ionization followed by mass separation with the ISOLDE (CERN, Geneva) isotope separator. [...]

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. [...]

Detailed $\alpha$-decay study of $^{180}\mathrm{Tl}$
/ Andel, B (Comenius U.) ; Andreyev, A N (York U., England ; JAEA, Ibaraki ; CERN) ; Antalic, S (Comenius U.) ; Barzakh, A (St. Petersburg, INP) ; Bree, N (Leuven U.) ; Cocolios, T E (Leuven U. ; CERN) ; Comas, V F (Darmstadt, GSI) ; Diriken, J (Leuven U.) ; Elseviers, J (Leuven U.) ; Fedorov, D V (St. Petersburg, INP) et al.
A detailed $\alpha$-decay spectroscopy study of $^{180}\mathrm{Tl}$ has been performed at ISOLDE (CERN). $Z$-selective ionization by the Resonance Ionization Laser Ion Source (RILIS) coupled to mass separation provided a high-purity beam of $^{180}\mathrm{Tl}$. [...]

Shape coexistence in $^{180}$Hg studied through the $\beta$ decay of $^{180}$Tl
/ Elseviers, J (Leuven U.) ; Tsekhanovich, I (CENBG, Gradignan) ; Diriken, J (Leuven U.) ; Patronis, N (Leuven U. ; Ioannina U.) ; Koster, U (Laue-Langevin Inst.) ; Franchoo, S (Orsay, IPN) ; Vermote, S (Gent U.) ; Bree, N (Leuven U.) ; Veselsky, M (Bratislava, Inst. Phys.) ; Huyse, M (Leuven U.) et al.
The beta(+)/EC decay of (180)Tl and excited states in the daughter nucleus (180)Hg have been investigated at the CERN On-Line Isotope Mass Separator (ISOLDE) facility. Many new low-lying energy levels were observed in (180)Hg, of which the most significant are the 0(2)(+) at 419.6 keV and the 2(2)(+) at 601.3 keV. [...]

Evolution of fission-fragment mass distributions in the neutron-deficient lead region
/ 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.

$β$ -delayed fission of isomers in $^{188}$Bi
/ Andel, B (Leuven U. ; Comenius U.) ; Andreyev, A N (York U., England ; JAEA, Ibaraki) ; Antalic, S (Comenius U.) ; Al Monthery, M (York U., England) ; Barzakh, A (St. Petersburg, INP) ; Bissell, M L (Manchester U.) ; Chrysalidis, K (CERN) ; Cocolios, T E (Leuven U.) ; Cubiss, J G (York U., England) ; Day Goodacre, T (Manchester U. ; CERN) et al.
$β$-delayed fission ($β$DF) decay of a low-spin (ls) and a high-spin (hs) isomer in $^{188}$Bi was studied at the ISOLDE facility at CERN. Isomer-selective laser ionization and time gating were employed to investigate each isomer separately and their $β$DF partial half-lives were determined: $T_{1/2\mathrm{p},β\mathrm{DF}} (^{188}\mathrm{Bi^{ls}})=5.6(8)×10^3$ s and $T_{1/2\mathrm{p},β\mathrm{DF}} (^{188}\mathrm{Bi^{hs}})=1.7(6)×10^3$ s.

$\beta$-delayed fission and $\alpha$ decay of $^{196}$At

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. [...]

The exotic decay process of β-delayed fission (βDF) has been studied in the neutron-deficient isotope Am230. The Am230 nuclei were produced in the complete fusion reaction Pb207(Al27,4n)Am230 and separated by using the GARIS gas-filled recoil ion separator. [...]
