Charge Radius of Neutron-deficient ${}^{54}$Ni and Symmetry Energy Constraints Using the Difference in Mirror Pair Charge Radii

Skyy V. Pineda, Kristian König, Dominic M. Rossi +8

The nuclear root-mean-square charge radius of ${}^{54}$Ni was determined with collinear laser spectroscopy to be $R{(}^{54}$Ni) = 3.737\,(3)~fm. In conjunction with the known radius of…
