  In this paper, we use Martin and Coulomb-Linear potentials and solve
Lippman-Schwinger equation and then identify $b\bar{c}$ energy levels.
Moreover, we predict results for such energy levels as that of $t\bar{t}$ (in
its short half-life) which is not observed. We showed our results are
consistent with previous findings in literature. Also investigating spectrum of
eigen-values, we obtain stability interval for Yukawa-Linear potential.
