/ 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. [...]

PUMA, antiProton unstable matter annihilation
/ PUMA Collaboration
PUMA, antiProton Unstable Matter Annihilation, is a nuclear-physics experiment at CERN aiming at probing the surface properties of stable and rare isotopes by use of low-energy antiprotons. Low-energy antiprotons offer a very unique sensitivity to the neutron and proton densities at the annihilation site, i.e. [...]

/ Barzakh, A E (St. Petersburg, INP) ; Andreyev, A N (York U., England ; JAERI, Tokai) ; Atanasov, D (Heidelberg, Max Planck Inst.) ; Cubiss, J G (York U., England) ; Harding, R D (York U., England ; CERN) ; Al Monthery, M (York U., England) ; Althubiti, N A (Manchester U. ; Al Jouf U.) ; Andel, B (Comenius U. ; Leuven U.) ; Antalic, S (Comenius U.) ; Ballof, J (CERN ; Mainz U., Inst. Kernchem.) et al.
The yield of 18 ion beams of radioactive gold nuclei produced in the thick uranium target at ISOLDE (CERN) by 1.4-GeV protons was measured. The production-efficiency dependence on the half-life (efficiency curve) was derived using the in-target production calculations by the FLUKA-CERN code. [...]

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 $^{176}Ir$. [...]

Shape coexistence in $^{187}$Au studied by laser spectroscopy

Hyperfine-structure parameters and isotope shift of the 9/2$^−$ isomeric state in $^{187}$Au relative to $^{197}$Au for the 267.6-nm atomic transition have been measured for the first time using the in-source resonance-ionization spectroscopy technique. The magnetic dipole moment and change in the mean-square charge radius for this 9/2$^−$ isomer have been deduced. [...]

The strength of the $N$ = 28 magic number in neutron-rich argon isotopes is examined through high-precision mass measurements of $^{46-48}$Ar, performed with the ISOLTRAP mass spectrometer at ISOLDE/CERN. The new mass values are up to 90 times more precise than previous measurements. [...]

Hyperfine-structure constants for the 6s2S1/2 and 6p2P1/2 atomic states of the Iπ=11/2− gold isomers Aum177,191,193,195 have been measured at CERN-ISOLDE, using the in-source laser resonance-ionization spectroscopy technique.

We probe the $N=82$ nuclear shell closure by mass measurements of neutron-rich cadmium isotopes with the ISOLTRAP spectrometer at ISOLDE-CERN. The new mass of $^{132}$Cd offers the first value of the $N=82$, two-neutron shell gap below $Z=50$ and confirms the phenomenon of mutually enhanced magicity at $^{132}$Sn. [...]
