A systematic study of the ground state properties of W, Os and Pt isotopes using HFB theory

Abstract

A systematic study of the ground state properties of transitional nuclei W, Os and Pt is conducted with the help of Skyrme Hartree-Fock-Bogoliubov theory. Different Skyrme interactions are employed in the study. Two different bases, harmonic oscillator and transformed harmonic oscillator, are used in our investigation. 2n-separation energy, charge radii, neutron and proton rms radii, neutron skin thickness and deformation parameter have been estimated. The results obtained are in good agreement with the available experimental values.

Theoretical Description of even- even Platinum Pt-186 nucleus using IBM and (VMI) Models

“…the case where the depairing of two quasi particles, which may couple with the collective rotation to produce a new band, this effect leads to back-bending phenomena [10]. Many researchers have been interested in studying the phenomenon of backbending using different methods, including Regan(2003) [10] who used the E-Gos method by drawing the relation between the transitional energy E over spin ( ) for two successive levels and the spin (J).Some theoretical researchers have recently focused on studying the nuclear properties of platinum isotopes, including N. Ashok and A.Joseph(2019) [11] studied the ground state properties of Pt isotopes with the help of Skyrme-Hartree-Fock-Bogoliutov (HFB)theory by using harmonic oscillator H.O. and transformed harmonic oscillator T.H.O.…”
