The central-depression parameter is determined by fitting the charge density distributions in lead isotopes to a three-parameter Fermi distribution. The central-depression parameter increases with the number of neutrons due to the isovector coupling channel of the nuclear interaction and its dependency on density.
21.10.Ft - Charge distribution.
27.80.+w - 190 A 219.
21.30.Fe - Forces in hadronic systems and effective interactions.
