Abstract

Doubly magic nuclei have a simple structure and are the cornerstones for entire regions of the nuclear chart. Theoretical insights into the supposedly doubly magic Ni78 and its neighbors are challenging because of the extreme neutron-to-proton ratio and the proximity of the continuum. We predict the Jπ=21+ state in Ni78 from a correlation with the Jπ=21+ state in Ca48 using chiral nucleon-nucleon and three-nucleon interactions. Our results confirm that Ni78 is doubly magic, and the predicted low-lying states of Ni79,80 open the way for shell-model studies of many more rare isotopes.
