Description
The correlation between the charge radii differences in mirror nuclei pairs and the neutron skin thickness has been studied with the so-called finite-range effective interaction over a wide mass region. The so far precisely measured charge radii differences data within their experimental uncertainty ranges in $^{34}$Ar-$^{34}$S, $^{36}$Ca-$^{36}$S, $^{38}$Ca-$^{38}$Ar and $^{54}$Ni-$^{54}$Fe mirror pairs are used to ascertain an upper limit for the slope parameter of the nuclear symmetry energy
$L\approx$100 MeV. This limiting value of $L$ is found to be consistent with the upper bound of the NICER PSR J0704+6620 constraint at 1$\sigma$ level for the radius R$_{1.4}$ of the 1.4M$_\odot$ neutron
stars. The lower bound of the NICER $R_{1.4}$ data constraints the lower limit of $L\approx$70 MeV. Within the range for $L$=70-100MeV the tidal deformability $\Lambda^{1.4}$ extracted from the GW170817 event at 2$\sigma$ level and the recent PREX-2 and CREX data on the neutron skin thickness are discussed.
