Surface properties of exotic isotopic chains using relativistic mean-field formalism

Abstract

The density-dependent nuclear symmetry energy (NSE) characterizes the variation of the binding energy with the change in the isospin asymmetry (ratio of the number of neutrons to that of protons). NSE and its related observables play a crucial role in understanding the various branches of nuclear physics and astrophysics, such as analyzing the nuclear structure of exotic nuclei, experiments on heavy-ion collision, supernova, and neutron stars study. In this theoretical study, we study the density-dependent isospin properties of finite nuclei of Odd-A isotopes of Scandium (Z=21) and Even-Even isotopes of Titanium (Z=22) for non-linear NL3 and density-dependent DD-ME2 parameters within the relativistic mean-field formalism. Using the coherent density fluctuation method, we calculate the weight function. Moreover, we investigate the symmetry energy as a function of the neutron number along the isotopic chain of Scandium and Titanium nuclei. This theoretical approach opens new avenues in understanding and predicting newer magicity along the drip-line for the different isotopic chains of nuclei.
