The current research intends to investigate the shape evolution and ground-state properties of even-even isotopic chains of Oxygen (Z = 8, N = 12 - 28), Calcium (Z = 20, N = 34 - 60), Nickel (Z = 28, N = 48 - 80), and Tin (Z = 50, N = 100 - 134) by using the DD-PCX parameterization based on covariant density functional theory. The covariant density functional theory is a popular theoretical tool for the description of nuclear structure phenomena. The nuclear properties of interest are potential energy surfaces, the binding energy per nucleon, two-neutron separation energy, differential variation of two-neutron separation energy, neutron rms radius, protons rms radius, and neutron skin thickness. The Covariant mass data and Skyrme mass data were very helpful to provide a comparative ground for better comparison of our data and testing the efficiency of DD-PCX parameterization. The effective interaction DD-PCX was designed to accurately calculate the neutron-skin thickness, and the comparative analysis present in the result section demonstrates that. We have observed the shape transition from spherical to oblate and oblate to spherical for Ni-60(Z=28, N=32) and Ni-66(Z=28, N=38) in our studies. We have observed the oblate shape in Ni-60, Ni-62, and Ni-64. (C) 2022 Elsevier B.V. All rights reserved.
