The project aims to study the hyperfine structure of radioactive ions by using the innovative radiofrequency spectroscopy method. The missions entrusted will be to study and develop this new radiofrequency spectroscopy technique around the S3-LEB gas jet, and to access the octupolar magnetic moment of the nucleus via a very high-precision measurement of the hyperfine structure.

Activities: In this project you will study the hyperfine structure of natural dysprosium and you will measure its magnetic octupolar moment. This measurement will be done for the first time using the Laser radiofrequency Double Resonance spectroscopy technique, a method that combines laser spectroscopy and radiofrequency excitation. These measurements will be carried out in the ALTISA laser room at GANIL, in Caen, France. In parallel you will take leadership in implementing this new spectroscopy method to the supersonic gas-jet environment of S3-LEB. The goal is to prepare a future measurement of the octupolar magnetic dipole moment of radioactive dysprosium isotopes produced by the GANIL new generation spectrometer S3. This work will be in close collaboration with research teams working at LPC Caen and GANIL, in France, but also the research teams from IKS (Instituut voor Kern- en Stralingsfysica) at KU Leuven University in Belgium. In the framework of this position, you will be in charge of carrying out the various tests and measurements, and to analyze and publish the scientific results as well as the technical development in peer-reviewed scientific journals. You will also be strongly involved in the last remaining commissioning phases of the experimental setup S3-LEB, a tool dedicated to laser spectroscopy and mass spectrometry of exotic nuclei. S3-LEB is one of the two experimental setups that will be installed at S3 focal plane, a new generation spectrometer currently under development at GANIL, France. S3-LEB has been commissioned off-line at LPC Caen and is currently being installed at GANIL. The first tests with radioactive beams are foreseen mid 2028. In this project you will have the chance to collaborate with world experts in nuclear physics (working at different facilities such as LPC Caen and GANIL in France, or KU Leuven in Belgium, but also at GSI-FAIR in Germany, Jyväskylä in Finland or at CERN), and you will work on answering the still open questions in nuclear structure or nuclear astrophysics. Furthermore, you will be encouraged and supported for any interest and scientific questions and technical development you would like to address which are related to low-energy nuclear physics or atomic physics.

PhD or equivalent, The candidates are expected to:

• Have a PhD in nuclear physics, atomic physics or a related field.
• To have experience in experimental techniques related to ion and atom manipulation at low energy. Knowledge of laser spectroscopy and/or mass spectrometry would be considered a plus.
• It is also expected to have basic knowledge of statistical physics and coding with python/C++/Matlab.
• A high proficiency in spoken and written English.
• You are expected to communicate your results by writing manuscripts and giving presentations at international conferences.

The successful candidate will be assigned to the S3-LEB team of the MPBE group, within the Corpuscular Physics Laboratory of Caen. We care deeply about providing an open and inclusive environment, and prioritize the professional developments and wellbeing of our postdoctoral fellows. The LPC CAEN, with about 100 staff, is a joint research unit (UMR 6534) under the supervision of three institutions: the CNRS, the University of Caen Normandy (UCN) and the Ecole Nationale Supérieure d’Ingénieurs de Caen (ENSICAEN). It is located on Campus 2 of the University of Caen (Campus Côte de Nacre) and is part of the research park of ENSICAEN (www.lpc-caen.in2p3.fr/).
