Theoretical Estimations of the Spin – Averaged Mass Spectra of Heavy Quarkonia and Bc Mesons

In this work, the spin-averaged mass spectra of heavy quarkonia and B_c mesons in a Cornell potential is studied within the framework of nonrelativistic Schrödinger equation. The energy eigenvalues and eigenfunctions are obtained in compact forms for any l-value using Nikiforov-Uvarov method. Based on the results determined the mass spectra of charmonium, bottomonium and B_c mesons. Our results are in good correspondence with other experimental and theoretical studies.
