The LISA project at CERN-ISOLDE
The LISA project at CERN-ISOLDE The LISA (Laser Ionisation and Spectroscopy of Actinides) consortium aims to train a new generation of experts in radioactive ion beam research and applications, laser spectroscopy, scientific laser technologies and atomic theorists whilst they work towards the goal of vastly improving our understanding of the atomic and nuclear properties of

ISOLDE’s Solenoidal Spectrometer (ISS): a new tool for studying exotic nuclei
ISOLDE's Solenoidal Spectrometer (ISS): a new tool for studying exotic nuclei The majority of atomic nuclei exist away from the valley of beta-stability, so it is perhaps unsurprising that in studying them nuclear physicists have discovered emerging phenomena not seen in stable nuclei. Changing shell structure, evolving nuclear shapes, and weak-binding phenomena such as halo

The many faces of ISOLDE
The many faces of ISOLDE You will stand across the street from the ISOLDE facility, when visiting CERN’s medical center, fire fighters, raw materials store, transport teams, or goods reception service. Located centrally at the Meyrin site (https://videos.cern.ch/record/2243399), ISOLDE has been the longest running CERN research facility, approved in 1964, connected to the synchrocyclotron (SC)

ISOLDE determines precise nuclear moments by devising novel experimental technique
ISOLDE determines precise nuclear moments by devising novel experimental technique Nuclear quadrupole moments (Q), a measure of charge asymmetry in nuclei, are experimentally accessible via the quadrupole interaction frequency νQ=eQVzz/h. To extract Q from this information one needs to know Vzz, the electric-field gradient at the nuclear site. This must come from theory, to date

Secrets of beta decay unraveled at ISOLDE
Secrets of beta decay unraveled at ISOLDE Ernest Rutherford, in 1899, separated radioactive emissions into two types: alpha and beta. Becquerel, in 1900, measured the mass-to-charge ratio of beta particles and identified them as electrons. The theory of β decay was developed by Fermi in 1934. However, even now predicting the half-life of beta decaying

Pinpointing the structure of the SnV centre in diamond using emission channelling at ISOLDE
Pinpointing the structure of the SnV centre in diamond using emission channelling at ISOLDE Diamond – beyond its allure as a jewel – exhibits an array of unique physical characteristics such as its hardness, the highest room thermal conductivity of any material (while being electrically insulating when undoped); it can also be doped to produce

Exotic radioactive molecules could reveal physics beyond the Standard Model
Exotic radioactive molecules could reveal physics beyond the Standard Model The first spectroscopic study of radium monofluoride (RaF) suggests that these radioactive molecules can be used to perform high precision tests of the Standard Model of particle physics. The study was done at ISOLDE, CERN’s radioactive beam facility, by an international team of physicists and

ISOLDE dives deeper in the mystery of the odd-even staggering effect
ISOLDE dives deeper in the mystery of the odd-even staggering effect In a recent paper, to appear in Nature Physics in the next weeks (arXiv:1911.08765v3), the CRIS collaboration, located at the ISOLDE facility in CERN, presents measurements of charge radii of exotic copper isotopes that shed further light on one of the most pertinent open

PUMA: Exploring exotic nuclear phenomena with antimatter
PUMA: Exploring exotic nuclear phenomena with antimatter PUMA is a new experiment proposed at both the CERN AD and ISOLDE facilities, that would for the first time transport antiprotons trapped at AD/ELENA to ISOLDE, by carrying them in a trap loaded onto a truck. The antiprotons would then be used for nuclear physics experiments at

Finding the best candidates for atomic EDM searches
Finding the best candidates for atomic EDM searches The search for hints of new physics Beyond the Standard Model (BSM) calls for a combination of experimental strategies including both direct searches but also a number of very high-precision measurements of certain quantities looking for deviations that could be interpreted in the framework of BSM physics.
