In this work, heavy quarkonia (cc¹ and bb) properties (spin-averaged mass spectra, the wavefunction at the origin, the root mean square radius, the average heavy-quark velocity and the E1 radiative transition rates ) from three di®erent potential models V (r) = ¡ar + br¯; ¯ = 1; 2; 3; are extracted using the QQ-onia package and using analytic method based on a Nikiforov-Uvarov Method. The potential parameters are determined from the 1S and 2S states and by employing the virial theorem for the potential models with ¯ = 1; 2, while for the ¯ = 3 model, we used the energy eigenvalue obtained from the NU method instead of using the virial theorem. The results are compared with the available experimental data. It is found that the three models are in good agreement with the available experimental data. |
