“…In this spectrum, the transitions from the low-spin states decaying to the ground state are clearly identified. The transition with an energy of 2485keV is the decay of the -19 2 excited state of 207 Pb built on top of the + 13 2 isomer [13,14]. This isomer at 1633keV is suggested to be built on the neutron-hole ni 13 2 .…”

The multi-nucleon transfer reaction mechanism was used to produce and study nuclei in the vicinity of 208 Pb. This mass region is a test case for the nuclear shell model. The mass identification of the fragments was performed with the large acceptance magnetic spectrometer VAMOS++ coupled to the AGATA γ-tracking array. This experiment aimed to determine both lifetimes and gyromagnetic ratios of excited states with the Cologne plunger device. The analysis indicates promising results with the possibility to determine several new lifetimes in this region.

“…The corresponding states, 13/2 + and 7/2 − , are well studied and found to have a dominant single-particle character. At variance, the 2485 keV transition from the decay of the 19/2 − state to the 13/2 + state, was found to have an E3 character [172]. The 13/2 + , 7/2 − , and 19/2 − states were analyzed in terms of particle-octupole-vibration coupling in [173] using the experimentally known energies and assuming the dominance of the above-mentioned orbitals.…”

The Advanced GAmma Tracking Array (AGATA), the new generation high-resolution γray spectrometer, has seen the realization of the first phases of its construction and exploitation. A number of nuclear structure studies based on experiments utilizing the principle of γ -ray tracking were carried out in this decade. The combination of highest detection efficiency and position sensitivity allowed very selective spectroscopic studies with stable beams and the use of instable ion beams with the lowest intensities. Nuclear-structure studies commenced already at INFN-LNL (Legnaro, Italy) with a first implementation of the array consisting of five AGATA modules. A larger array of AGATA modules was used at GSI (Darmstadt, Germany) for experiments with unstable ion beams at relativistic energies. The spectrometer was then mounted in a beam line at GANIL (Caen, France). This review discusses several of the obtained results, underlying the progress made and future perspectives. The performed experiments give insights into nuclear structure issues which are connected to single particles, collective degrees of freedom, nucleon interactions and symmetries. Most of the investigated nuclei are located outside the stability line and for stable nuclei the investigations concern unexplored configurations. Altogether the obtained results represent advances which could test theory in exclusive way and motivate new theoretical developments.Opportunities for further γ -ray spectroscopy with the foreseen more advanced phase of the AGATA emerge in the discussions of the presented data.
