Description
Summary:The nuclear charge radius of \(^{32}\)Si was determined using collinear laser spectroscopy. The experimental result was confronted with ab initio nuclear lattice effective field theory, valence-space in-medium similarity renormalization group, and mean field calculations, highlighting important achievements and challenges of modern many-body methods. The charge radius of \(^{32}\)Si completes the radii of the mirror pair \(^{32}\)Ar - \(^{32}\)Si, whose difference was correlated to the slope \(L\) of the symmetry energy in the nuclear equation of state. Our result suggests \(L \leq 60\)\,MeV, which agrees with complementary observables.
