More about the position
The research of the Nuclear Physics group is focused on the study of atomic nuclei under extreme conditions, e.g. nuclei at high excitation energy at the transition from quantum order to chaos, exotic nuclei with an unusual ratio of protons and neutrons, and nuclear reactions in astrophysical environments. To obtain experimental information under such conditions is crucial in order to constrain and improve theoretical nuclear structure models, and to understand how elements heavier than iron are formed in explosive stellar environments.
The present PhD project aims at studying nuclear shapes and shape coexistence in exotic nuclei by measuring electromagnetic transition probabilities using gamma-ray spectroscopy in combination with lifetime measurements. Detailed transition probabilities, obtained over a wide range of nuclides under the same experimental conditions, allow systematic comparisons with state-of-the-art theoretical calculations. The rapid change of nuclear deformation with proton and neutron number, the occurrence of shape coexistence, and the importance of the triaxial degree of freedom make nuclei around proton and neutron numbers and very sensitive benchmarks for theoretical models.
The project aims at performing lifetime measurements for neutron-rich fission fragments in this mass region using the recoil-distance Doppler shift (RDDS) and fast timing techniques following fusion-fission reactions. The successful applicant will analyze data obtained with the gamma-ray tracking detector AGATA and the fast-timing array FATIMA coupled to the magnetic spectrometer VAMOS. The candidate is expected to contribute to the further development of relevant data analysis techniques and software frameworks. The data analysis furthermore requires Monte Carlo simulations of the detector responses within the GEANT4 framework. The experimental results will be compared to theoretical calculations, which will be partly performed by the candidate and partly in collaboration with international partners. It is foreseen to complement the study of nuclear shapes with additional lifetime measurements and Coulomb excitation experiments with radioactive ion beams, to which the candidate is expected to contribute.
