The sudden onset of deformation in $A\approx100$ nuclei at $N=60$ has been described as a ground-state shape transition that has raised a lot of interest over the years from an experimental and theoretical point of view. This transition is most pronounced in the Zr and Sr isotopic chains where the low-energy excited-state structure shows significant signs of deformation developing at $N=60$,...
One of the long standing questions in the standard model of particle physics is the origin of nucleon mass, spin, and the charge and density spatial distributions within. In the theory of the strong interaction, the structure of the nucleon is described by form factors which can be accessed through hard exclusive meson production. The main focus of this study is to measure the form factor of...
Type I X-ray bursts are among the most frequent thermonuclear explosions we can observe, and can reveal important properties of accreting neutron star systems. Understanding their light curves requires detailed knowledge of the nuclear reactions that enable the transition from the hot CNO cycle towards explosive burning and the rp process. One such key breakout reaction is the 14O(α,p)17F...
A sudden ground-state shape transition is known to occur sharply at $N=60$, accompanied by equally dramatic changes in the low-energy spectra of the nuclei with A$\approx\!$100. Detailed spectroscopic data on the $\gamma$ decay of $^{100}$Zr are essential for understanding this phase transition and the emergence of shape coexistence, predicted by recent Monte Carlo Shell Model (MCSM)...
As nuclei get richer in neutrons, the Q-value for beta-decay gets larger while the neutron separation energy decreases. Consequently, for large enough N/Z ratios, the daughter nucleus can decay by emitting one to several neutrons. Directly studying states above the neutron separation energy is an experimental challenge as it requires neutron detectors that have a good energy resolution while...
