Gamma and fast-timing spectroscopy of exotic tin isotopes around 132Sn

The evolution of the nuclear shell structure for nuclei with large neutron to proton ratios is an open problem in contemporary nuclear physics research. The study of the regions around exotic doubly-magic nuclei plays an important role in the understanding of how shell structure evolves, and provides key input for theoretical calculations, which can be then used over larger areas of the nuclear chart. The present PhD work is focused on the study of the nuclear structure in the region around 132Sn (Z=50 and N=82), the heaviest doubly-magic nucleus away from stability within reach at current experimental facilities. The nucleus 132Sn itself is of importance for the description of the exotic nuclear region around N = 82 and to provide insight into particle-hole couplings for both protons and neutrons. The nuclei with a valence particle or hole around 132Sn are relevant for investigating the single-particle states in the region, and the matrix elements of the electromagnetic transitions interconnecting them..
