Study of two-proton radioactivity within the relativstic mean-field plus bcs approach

Abstract

Encouraged by the success of RMF+BCS approach for the description of the ground state properties of the chains of isotopes of proton magic nuclei with proton number \textit{Z}=8, 20, 28, 50 and 82 as well as those of proton sub-magic nuclei with \textit{Z}=40, we have further employed it, in an analogous manner, for a detailed calculations of the ground state properties of the neutron magic isotones with neutron number \textit{N} = 8, 20, 28, 50, 82 and 126 as well as those of neutron sub-magic isotones with \textit{N} = 40 using the TMA force parameterizations in order to explore low lying resonance and other exotic phenomenon near drip-lines. The results of these calculations for wave-function, single particle pairing gaps etc. are presented here to demonstrate the general validity of our RMF+BCS approach. It is found that, in some of the proton-rich nuclei in the vicinity of the proton drip-line, the main contribution to the pairing correlations is provided by the low-lying resonant states, in addition to the contributions coming from the states close to the Fermi surface, which results extended proton drip-line for isotonic chain.
