Deformation versus Sphericity in the Ground States of the Lightest Gold Isotopes
/ 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. [...]

Isomeric excitation energy for $^{99}$In$^{m}$ from mass spectrometry reveals constant trend next to doubly magic $^{100}$Sn
/ Nies, L. (CERN ; Greifswald U.) ; Atanasov, D. (CERN) ; Athanasakis-Kaklamanakis, M. (CERN ; Leuven U.) ; Au, M. (CERN ; Mainz U.) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Dobaczewski, J. (Warsaw U.) ; Hu, B.S. (TRIUMF) ; Holt, J.D. (TRIUMF ; McGill U.) ; Karthein, J. (MIT) ; Kulikov, I. (Darmstadt, GSI) et al.
The excitation energy of the 1/2$^-$ isomer in $^{99}$In at ${N=50}$ is measured to be 671(37) keV and the mass uncertainty of the 9/2$^+$ ground state is significantly reduced using the ISOLTRAP mass spectrometer at ISOLDE/CERN. The measurements exploit a major improvement in the resolution of the multi-reflection time-of-flight mass spectrometer. [...]

The Einstein classical Weak Equivalence Principle states that the trajectory of a particle is independent of its composition and internal structure when it is only submitted to gravitational forces. This fundamental principle has never been directly tested with antimatter. [...]

The empirical shell gap revisited in light of recent high precision mass spectrometry data
/ Manea, Vladimir (IJCLab, Orsay) ; Mougeot, Maxime (CERN ; Heidelberg, Max Planck Inst. ; Jyvaskyla U.) ; Lunney, David (IJCLab, Orsay)
We present an updated view on the phenomenon of mutually enhanced magicity based on the current experimental knowledge of atomic masses, including some recent precision measurements performed with the ISOLTRAP mass spectrometer at ISOLDE/CERN. We discuss the trends of the proton and neutron empirical shell gaps computed either in the standard approach, along chains corresponding to magic numbers of protons and neutrons, respectively, or along the neighbouring isotonic chains differing by two nucleon numbers. [...]

Observation of the radiative decay of the ${}^{229}\mathrm{Th}$ nuclear clock isomer

The nucleus of the radioisotope thorium-229 (${}^{229}$Th) features an isomer with an exceptionally low excitation energy that enables direct laser manipulation of nuclear states. For this reason, it is a leading candidate for use in next-generation optical clocks. [...]
