Abstract

The nuclear ground state and beta decay properties for ^156−162Nd have been investigated within the framework of the relativistic mean field (RMF) approach and proton-neutron quasi-particles random phase approximation (pn-QRPA) model. The RMF model with density-dependent interactions DDME2 and DDPC1 is utilized to analyze the potential energy curves (PECs), potential energy surfaces (PESs), the nuclear ground state deformation parameter (

β_{2}

), neutron (proton) separation energies (S_n(S_p) and S

_{2 n}

_{2 p}

)), neutron skin thickness (r

_{n p}

), and root mean square radius (r

_{r m s}

). Furthermore, the

β_{2}

computed via the finite range droplet model (FRDM) and RMF with DDME2 and DDPC1-based interactions are employed in the pn-QRPA model as an input parameter for the calculations of the beta decay properties, including the Gamow Teller (GT) strength, log ft values, and half-lives of ^156−162Nd. The FRDM and RMF-DDPC1-based calculated log ft values show better consistency with the measured data. The present computed beta decay half-lives are in reasonable agreement with the experimental data.
