he nuclear root-mean-square charge radius of was determined with collinear laser spectroscopy to be . In conjunction with the known radius of the mirror nucleus , the difference of the charge radii was extracted as . Based on the correlation between and the slope of the symmetry energy at nuclear saturation density ( ), we deduced . The present result is consistent with the from the binary neutron star merger GW170817, favoring a soft neutron matter EOS, and barely consistent with the PREX-2 result within error bands. Our result indicates the neutron-skin thickness of as 0.15–0.21 fm.
