**ABSTRACT:**A simple form of nonlinear self-coupling of the scalar meson field is introduced and suggests a new nucleon-nucleon (NN) potential in relativistic mean field theory (RMFT) analogous to the M3Y interaction. We investigate the ability of RMFT to reproduce nuclear ground state properties and the surface phenomena like proton radioactivity simultaneously with the proposed NN interaction. The results obtained agree reasonably well with the widely used M3Y NN interactions and the experimental data in this first application of nucleon-nucleon potential.Physical Review C 02/2014; 89(3). · 3.88 Impact Factor -

**ABSTRACT:**This paper refers to an another attempt to search for spherical double shell closure nu- clei beyond Z=82, N=126. All calculations and results are based on a newly developed approach entitled as simple effective interaction. Our results predict the combination of magic nucleus occurs at N=182 (Z=114,120,126). All possible evidences for the oc- currence of magic nuclei are discussed systematically. And, the obtained results for all observables compared with the relativistic mean field theory for NL3 parameter.International Journal of Modern Physics E 01/2014; 23(03). · 0.84 Impact Factor - [Show abstract] [Hide abstract]

**ABSTRACT:**The ground state and first intrinsic excited state of superheavy nuclei with Z = 120 and N = 160–204 are investigated using both nonrelativistic Skyrme–Hartree–Fock (SHF) and the axially deformed relativistic mean field (RMF) formalisms. We employ a simple BCS pairing approach for calculating the energy contribution from pairing interaction. The results for isotopic chain of binding energy (BE), quadrupole deformation parameter, two neutron separation energies and some other observables are compared with the finite range droplet model (FRDM) and some recent macroscopic–microscopic calculations. We predict superdeformed ground state solutions for almost all the isotopes. Considering the possibility of magic neutron number, two different modes of α-decay chains 292120 and 304120 are also studied within these frameworks. The Qα-values and the half-life for these two different modes of decay chains are compared with FRDM and recent macroscopic–microscopic calculations. The calculation is extended for the α-decay chains of 292120 and 304120 from their excited state configuration to respective configuration, which predicts long half-life (in seconds).International Journal of Modern Physics E 11/2012; 21(11). · 0.84 Impact Factor
