Shape evolution in Palladium isotopic chain

In this study, we explore the phenomenon of shape evolution in eveneven ^96-130Pd isotopes, employing the covariant density functional theory with two different parameterizations: the density-dependent meson-exchange DDME2 and the density-dependent point-coupling DD-PC1. This investigation is done on the basis of the evolution of the ground state shapes obtained within the axial and triaxial potential energy surface calculations. The shape transition in the palladium isotopic chain is conspicuously evident and distinct. Furthermore, various ground-state properties, including binding energy, two-neutron separation energy (S_2n), charge radii, and two-neutron shell gap (δ_2n), have been carefully calculated and found to be in good agreement with the available experimental data. Also, a strong shell closure is clearly seen at the magic neutron number N = 82. (author)
