A recent survey extracted the implied effective $E2$ charges from $B(E2;2_1^+ \rightarrow 0_1^+)$ values in doubly magic nuclides plus or minus two like nucleons [1]. A similar survey of the effective $g$ factors in the $M1$ operator as determined empirically from the magnetic moments of nuclei adjacent to closed shells will be presented. The patterns will be discussed and compared with...

Single-j calculations for (𝑗)𝑛 configurations with n = 3,..,2j+1 can be performed using a semi-empirical approach, provided that the energies and absolute electromagnetic transition rates are known for the two-particle (hole) nucleus. This approach was already successfully applied in the case of protons in the (𝜋ℎ9/2)3 nucleus 211𝐴𝑡 [1]. At the Cologne Tandem Accelerator of the Institute for...

In the last decade, a considerable progress in the understanding of the structure of nuclei in the vicinity of $^{132}$Sn, the heaviest doubly-magic nucleus far-off stability accessible for experimental studies, was achieved. The many results obtained in several experimental campaigns performed at the Radioactive Isotope Beam Facility (RIBF) in Japan, in combination with state-of-the-art...

Recently, our understanding of three-nucleon forces (3NFs) in nuclei was notably advanced by the advent of the chiral effective field theory [1], which offers a systematic and unified approach to constructing two-body forces (2NFs) and 3NFs on equal footing. These modern 3NFs and 3NFs have been extensively utilized in many-body calculations, firmly establishing the role of 3NFs in describing...

EURO-LABS is a European project, which brings together, for the first time, the three research communities of nuclear physics, accelerator and detector technologies for high energy physics, in a pioneering super-community of sub-atomic scientists. It is a network of 33 research and academic institutions from 18 countries (25 beneficiaries and 8 associated partners) from European and non-EU...

Many-body Green's function theory stands out among ab initio methods because of its capability of computing a large set of observables, ranging from ground state properties, to response and single particle spectroscopy. The advantage is the capability of connetcting different aspects of the many-body correlations and dynamics of a given nucleus within the same microscopic framework.
