Description of the thesis topic
« Gamma-ray spectroscopy of exotic nuclei produced with AGATA: Analysis and development of analysis methods.»
The "nuclear matter" team at IP2I specializes in high-resolution gamma-ray spectroscopy focused on the effects of deformation on spin, isospin or excitation energy in atomic nucleus under extreme conditions. It is therefore natural that we have been involved in the AGATA collaboration since its
inception. The responsibilities of our team within the collaboration are focused on analytical methods (software and data processing). Before it's departure from GANIL in mid 2021, a long period of data collection with multiple sources has been carried out. AGATA will then move to Legnaro for a new period of operation.
The PhD student will have the opportunity to participate in the installation of AGATA at Legnaro as well as be part of the new experimental campaign. He/she will be directly involved within the AGATA collaboration to participate in the experiments and analyze the produced data. The thesis will consist of a part focused on the key algorithms of the multi-detector (PSA, Tracking) either by exploiting simulated data, through the Geant4 software, and/or data taken on site. Original approaches (Machine Learning) will be considered for data processing.
The new possibilities provided by the Legnaro accelerator, associated with AGATA, should allow to perform spectroscopy of many nuclei in particular those located in the rare earth region (Z~60), known to host extreme nuclear deformations: the candidate could have opportunities to analyze the experiments in which he/she will participate. Coupled studies with data taken from other multigamma detectors are possible. An interaction with the IP2I theory group should allow to compare the results obtained with the theoretical models developed in Lyon.
The work, carried out at the IP2I laboratory in Lyon in the experimental nuclear physics group, will mainly consist of analyzing data linked to gamma-ray multi-detectors installed at major European infrastructures. Trips to the experimental sites for data collection are to be planned. The results obtained will be presented in national and international workshops/conferences which may take place anywhere in the world but probably in Europe.
The thesis is under the supervision of
Dr. Olivier Stézowski (DR CNRS/IP2I, HDR, thesis supervisor) and Dr. Jérémie Dudouet (CR CNRS/IP2I, co-supervisor).
