In the nuclear chart the Nickel isotopic chain offers a unique opportunity to study the interplay between single-particle and collective excitations in atomic nuclei, for which important observables are the energy of the first 2$^+$ excited state in even-even nuclei and the reduced transition probability B(E2; 2$^+ \rightarrow 0^+$). The B(E2) can be indirectly measured via Coulomb Excitation...
The first $\gamma$-ray spectroscopy of $^{78}$Ni [1] and the recent studies on $^{79}$Zn [2,3], just below the N=50 shell closure, suggests that deformed intruder configurations could play a crucial role in low-energy structure properties in this region and towards the limits of the nuclear chart. Such configurations are predicted to originate from multiparticle-multihole excitations [4] above...
The $^{85}$Kr(d,p$\gamma$)$^{86}$Kr reaction has been carried out at 10 MeV/u in inverse kinematics at Argonne's ATLAS facility using the HELIOS spectrometer and the Apollo array. The neutron capture cross section on the radioisotope $^{85}$Kr (T$_{1/2}$ = 10.7 yr), an s-process branching point nucleus, carries a significant uncertainty due to the challenges of direct measurements. However,...
