/ Cubiss, J G (York U., England) ; Andreyev, A N (York U., England ; JAEA, Ibaraki) ; Barzakh, A E (Unlisted) ; Van Duppen, P (KU Leuven, Dept. Phys. Astron.) ; Hilaire, S (CEA DAM) ; Péru, S (CEA DAM) ; Goriely, S (Brussels U., IAA) ; Al Monthery, M (York U., England) ; Althubiti, N A (Manchester U. ; Al Jouf U. ; Ain Shames U.) ; Andel, B (Comenius U.) et al.
The changes in mean-squared charge radii of neutron-deficient gold nuclei have been determined using the in-source, resonance-ionization laser spectroscopy technique, at the ISOLDE facility (CERN). From these new data, nuclear deformations are inferred, revealing a competition between deformed and spherical configurations. [...]

The extremely neutron-deficient isotopes $^{177,179}$Au were studied by means of in-beam γ -ray spectroscopy. Specific tagging techniques, α -decay tagging in $^{177}$Au and isomer tagging in $^{179}$Au, were used for these studies. [...]

Coulomb excitation of $^{222}$Rn
/ Spagnoletti, P (West Scotland U. ; Simon Fraser U., Dept. Chem.) ; Butler, P A (Liverpool U.) ; Gaffney, L P (Liverpool U. ; CERN) ; Abrahams, K (Western Cape U.) ; Bowry, M (West Scotland U. ; TRIUMF) ; Cederkäll, J (Lund U.) ; Chupp, T (U. Michigan, Ann Arbor) ; de Angelis, G (INFN, Legnaro) ; De Witte, H (Leuven U.) ; Garrett, P E (Guelph U.) et al.
The nature of quadrupole and octupole collectivity in $^{222}$Rn was investigated by determining the electric-quadrupole (E2) and octupole (E3) matrix elements using subbarrier, multistep Coulomb excitation. The radioactive $^{222}$Rn beam, accelerated to 4.23 MeV/u, was provided by the HIE-ISOLDE facility at CERN. [...]

High-spin states of $^{218}$Th
/ O'Donnell, D (SUPA, UK ; Liverpool U. ; IIT, Roorkee) ; Page, R D (Liverpool U.) ; Grahn, T (Jyvaskyla U.) ; Ali, F A (Liverpool U. ; Sulaimaniya U.) ; Auranen, K (Jyvaskyla U.) ; Capponi, L (SUPA, UK) ; Carroll, R J (Liverpool U.) ; Chishti, M M R (SUPA, UK) ; Drummond, M C (Liverpool U.) ; Greenlees, P T (Jyvaskyla U.) et al.
High-spin states in the $N = 128$ nucleus $^{218}$Th have been investigated following fusion–evaporation reactions, using the recoil-decay tagging technique. Due to the short-lived nature of the ground state of $^{218}$Th prompt $\gamma$ rays have been correlated with the $\alpha$ decay of the daughter nucleus $^{214}$Ra. [...]

Laser-assisted nuclear decay spectroscopy of $^{176,177,179}$Au
/ Harding, R D (York U., England ; CERN) ; Andreyev, A N (York U., England ; JAERI, Tokai) ; Barzakh, A E (St. Petersburg, INP) ; Cubiss, J G (York U., England) ; Van Duppen, P (Leuven U.) ; Al Monthery, M (York U., England) ; Althubiti, N A (Manchester U.) ; Andel, B (Leuven U. ; Comenius U.) ; Antalic, S (Comenius U.) ; Cocolios, T E (Leuven U. ; Manchester U.) et al.
A study of the laser-ionized and mass-separated neutron-deficient isotopes $^{176,177,179}$Au was performed using the Resonance Ionization Laser Ion Source and the Windmill detection setup at ISOLDE, CERN. New and improved data on complex fine-structure α decays of the three isotopes were deduced, providing insight into the low-lying levels in the daughter nuclei $^{172,173,175}$Ir. [...]

Laser-assisted decay spectroscopy and mass spectrometry of $^{178}\mathrm{Au}$
/ Cubiss, J G ; Andreyev, A N ; Barzakh, A E ; Manea, V ; Al Monthery, M ; Althubiti, N A ; Andel, B ; Antalic, S ; Atanasov, D ; Blaum, K et al.
A comprehensive study of the isotope $^{178}$ Au has been made at the CERN-ISOLDE facility, using resonance laser ionization. Two long-lived states in $^{178}$ Au were identified—a low-spin ground state and a high-spin isomer—each of which were produced as pure beams. [...]

A study of the ground states of the laser-ionized and mass-separated odd-odd isotopes $^{180,182}$Au was performed using the Resonance Ionization Laser Ion Source, Windmill detection setup and ISOLTRAP Multi-Reflection Time-of-Flight Mass Spectrometer at ISOLDE, CERN. A complex fine-structure α-decay pattern of $^{180}$Au was deduced, providing insight into the low-lying levels in the daughter nucleus $^{176}Ir$. [...]
