The INDRA-FAZIA group of GANIL and LPC Caen is looking for a post-doctoral collaborator to play a major role in the analysis of an experiment coupling the two charged particle detectors INDRA and FAZIA which took place at GANIL in 2019. He/she will also participate in new experiments that should take place in 2021. The FAZIA and INDRA collaborations are proposing an ambitious experimental program coupling these two devices whose goal is the most complete characterization to date of the formation and disintegration of hot nuclei produced during heavy ion collisions around Fermi energies.
The successful candidate will join the LPC Physics Laboratory. In order to better constrain the iso-vectorial part of the equation of state of nuclear matter and also to extract the effects in low nuclear density environment, he/she will be in charge of:
- The production of results from theoretical models adapted to the scientific purpose;
- The analysis of experimental data and their comparison with theoretical predictions.
He/she will also participate in the future INDRA-FAZIA experiments which should be carried out in 2021.
The candidate will have a PhD in nuclear physics and will have a proven track record in comparing data with model predictions. The successful candidate will also have good experience in analyzing multiparameter data.
In order to perform these tasks, the candidate must be familiar with the ROOT software and have C++ programming skills.
Over the last decades, the study of heavy ion collisions with the INDRA charged particle multidetector has led to major advances in the understanding of the dynamics and thermodynamics of nuclear matter, in particular:
- demonstrating the existence of different phases of nuclear matter;
- studying the transformations between these phases in the context of the thermodynamics of finite systems;
- studying the transport properties of nuclear material away from equilibrium.
Nevertheless, a crucial element is missing in most of the experimental results available today, the chemical composition of the reaction products (isotope resolution) which can only be measured for the lightest nuclei with INDRA. We still do not know how neutrons are distributed among the many fragments of intermediate mass (Z=5~20) produced by these collisions.
This is why the FAZIA and INDRA collaborations have developed an ambitious program using the coupling of these devices in order to achieve the most complete measurement possible to date of the formation and decay of hot nuclei in these reactions. FAZIA provides isotope identification of the nuclei up to Z=25 with a resolution close to that of a magnetic spectrometer but without any acceptance limit. 12 FAZIA blocks (192 telescopes in total) replace the first INDRA rings at the most forward angles in order to carry out experiments related to: collision dynamics (transport properties of asymmetric matter in the medium); equation of state and phase transition (symmetry energy); clustering phenomena (structural effects in the medium); secondary decay of hot exotic nuclei (isospin dependence of the density parameter of the nuclear level).
The successful candidate will join the physics laboratory of LPC, which has 35 permanent researchers, and will work in the INDRA-FAZIA research team composed of physicists from GANIL and LPC Caen, of which 2 are research directors, 4 are research fellows and 1 is a lecturer. The team also includes several PhD students.
Constraints and risks
The successful candidate will travel occasionally, mainly in France and Italy, to attend meetings of the INDRA/FAZIA collaborations. He/she will have the opportunity to travel for discussions with theoreticians. He/she will also have the opportunity to present the results of his/her work in international conferences around the world.
Please submit a motivation letter, a detailed CV and two letters of recommendation.
