A new Frontier of Unstable Doubly Magic Nuclei

Research output: Contribution to journalReview article


The doubly magic character of the isotope 78Ni was demonstrated experimentally. To accomplish this, a newly developed target and detector system was created to measure the de-excitation gamma rays following proton- knockout reactions. While the high energy of the first ex- cited state of 78Ni manifests its closed-shell nature, a second state found at a similar energy questions the nuclear shell robustness for nuclei with larger neutron-to-proton ratios. This result triggers further comprehensive studies to delineate the evolution from spherical to deformed nuclei at the extremes of the nuclear chart.
