Description of Energy Levels for 84,86,96,98Sr Isotopes

Resumo

The positive ground-state band (GSB) of ^84,86,96,98Sr has been calculated using the Bohr–Mottelson (BM) model, interacting vector boson model (IVBM), and interacting boson model (IBM-1), while the negative-parity band (NPB) of ^84,86,96,98Sr has been calculated using the BM model and IVBM. IBM-1 has been used to calculate the energy of the gamma and beta bands. To determine the properties of the ground-state band, the ratio (r(I +2)/I) and the E-GOScurve (E_γ/I) have been plotted as a function of the spin (I). The potential energy surface (PES) has been calculated using IBM-1. The contour plots of the PESs show that ^84,86,96Sr nuclei have vibrational properties and ⁹⁸Sr has rotational characteristics.
