Difference of mirror charge radii $^{\mathrm{36}}$Ca-$^{\mathrm{36}}$S and $^{\mathrm{38}}$Ca-$^{\mathrm{38}}$Ar, and implications on the neutron equation of state
ORAL
Abstract
The charge radii of mirror nuclei $^{\mathrm{36}}$Ca-$^{\mathrm{36}}$S and $^{\mathrm{38}}$Ca-$^{\mathrm{38}}$Ar were used to deduce he first derivative $L$ of the symmetry energy in the nuclear equation of state (EOS) [1]. Here the linear correlation between the difference of mirror charger radii and $L$ were used [2] to set constraint on $L$. Implications on $L$ will be discussed in terms of correlation with the mean field calculations with Skyrme interactions, the covariant density functional theory (CODF) and the Multi-Reference In-Medium Similarity Renormalization Group (IMSRG) approach.
