Neutron skin thickness (Rnp) of the atomic nuclei 48Ca, 132Sn and 208Pb are considered in the KIDS (Korea:IBS-Daegu-Sungkyunkwan) density functional formalism. Model parameters most relevant to Rnp are constrained from standard nuclear data and neutron star properties determined from modern observations. Mean values of Rnp are obtained as 0.161, 0.220 and 0.160 fm for 48Ca, 132Sn and 208Pb, respectively, and the corresponding standard deviations are 0.011, 0.020 and 0.021 fm. Correlations between Rnp of the three nuclei are considered, and we find that Rnp’s are correlated very strongly. We obtain correlation coefficient 0.978 between Rnp of 48Ca and 208Pb, and 0.996 between Rnp of 132Sn and 208Pb. 1 ar X iv :2 11 2. 00 99 6v 1 [ nu cl -t h] 2 D ec 2 02
