Description
We investigated the behavior of binding energy, two neutron separation energy, a differential variation of the separation energy and the abnormality in nuclear charge radius along the neutron-rich even-even isotopic chains of Ba nuclei. The relativistic mean field formalism with recently developed NL3* and density dependant DD-ME2 force parameters are used for the present analysis. The study further extended to obtain nuclear matter characteristics such as symmetry energy, neutron pressure and symmetry energy curvature using the density distribution via coherent density functional methods. We found some non-monotonic aspects can be correlated with the structural properties like shell/sub-shell closures in the isotopic chain at N=182. In addition to these, we have shown the internal configuration of these nuclei to get a further insight into the reason for this discrepancy.
